This weekend is San Diego Comic-Con, and if you're one of the lucky thousands of people who get to attend this year, you know what that means: get ready to spot all kinds of celebrities everywhere. From A-list movie stars to YouTube sensations to even just comic book artists you're obsessed with, everyone who is everyone is at SDCC.

But remember, the artists, writers, directors, actors, and creators who you love from afar, no matter how famous or beloved they are, are still just people — and as much as their livelihoods often depend on their fans, being around so many strangers who feel various degrees of entitlement over your work has got to be an exhausting experience.

It doesn't matter whether you're planning to hit up your favorite actor's autograph booth at a convention or you've just spotted them on the street: it's still important to make sure you're as respectful and chill as you can be, which is hard when it's your favorite person. Here are some tips and suggestions to help your almost-inevitable celebrity encounter go as smoothly as possible:

DO: Respect the rules of the space you're meeting them in.

At photo ops, it's sometimes considered rude to try to talk to the celebrity for too long because other people are waiting to do the same thing. At autograph tables, you might not be allowed to take pictures — it holds up the line and the space isn't set up well enough for that. At Q&A panels, you're expected to ask an actual question pertaining to their work. 

Every space at a convention has its own code of conduct, and it's important to make sure you know what's expected of you as a con-goer before you get there. Your behavior in those spaces doesn't just affect the talent, it affects the other convention attendees around you.

DON'T: Take stealth pictures of them.

Look — there's a celebrity over there, but you don't want to bother them! What if you pretended to be taking a selfie or a picture of something else, but also made sure the camera was pointed in their direction so it seemed like they were photobombing you? Whaaaat! What a crazy random thing to happen.

Yeah, you're definitely not the first person to try that with this celebrity. Not everybody is going to be annoyed by that move all the time (Bill Murray might even make faces back at you, so fair warning), but in general it's not fun to feel like people are taking pictures of you without your consent everywhere you go, so if you really need that picture it's better to ask them. 

Especially don't do this at autograph tables or other situations in which you're been asked by the convention not to take pictures, by the way. And the same rule applies for cosplayers, even the non-famous ones — asking for a photo is always better than being sneaky!

DO: Plan ahead!

If you know that your favorite actor is going to be at a convention and you just have to get a chance to talk to them, plan what you're going to say to them in advance. That way when you do get up close and the nerves kick in, you'll have a blueprint to follow. My friend Sam Maggs gives this extra-good advice in her book, "The Fangirl's Guide To The Galaxy":

"If the star is particularly well known in the nerd world for one thing, try to compliment his or her work in something obscure instead. Like, sure, you loved Tom Felton as Draco Malfoy, but if you tell him how much his performance in 'Belle' impressed you, I guarantee you'll see his face light up and get some new stories about him."

Planning ahead is especially important during paid photo ops, when you're only going to be able to get a couple of seconds with a person before you two have to take a picture together. For that, Maggs suggests doing a bit of online research ahead of time, and then deciding how to pose with your favorite according to how game they've been to pose with other fans in the past. Carrie Fisher, for example, is very game. Obviously. 

DON'T: Touch them without asking.

There are people everywhere at conventions, moving as slowly as possible and accidentally bumping into each other, and it's enough to make anybody anxious about germs (or even stampedes). Add to that being in a situation where you're required to have one-on-one time with a thousand people who all enjoy your work, and having a whole lot of hands and torsos coming at you for hugs and handshakes can be an incredibly stressful experience. 

A lot of celebrities have no-touching policies for that exact reason, but even when they don't, it's generally polite to wait until the other person initiates physical contact. If they don't and you're really craving some human touch, you can ask them if it would be alright. Don't get annoyed if they say no, though.

DON'T: Expect them to be the same kind of nerd as you are.

Some celebs are super huge fans of the thing they're in — if you happen to ask Ben Affleck what his favorite Batman comic is, for example, he might actually have an answer for you. But not everybody's like that, and certainly not everybody's required to be. Imagine if people insisted you should know everything about the history of "Star Wars" because you own a Darth Vader t-shirt, except all the time and even when you aren't wearing that shirt. It's kind of like that. 

Plus, you might actually end up spoiling the person on the very thing they're starring in. "Game Of Thrones" star Charles Dance found out just how he'd be leaving the show from a fan, for example:

"There was a guy in the street who came up to me and said ‘Game of Thrones,' brilliant, you’ve got a great death scene! And I said, 'Oh do I?' and he told me the manner of my death."

Dance took it in stride, but could you imagine how terrible that would be if he didn't already know he was leaving the show? Better to not even go there.

DON'T: Get pissed off when they want you to pay for things.

Some celebs are happy to sign whatever you put in front of them, no matter where you encounter them. Others prefer to charge an autograph fee; still others participate in photo sessions at conventions, which also usually cost money. And some go back and forth between all of these different options, because people are complex and don't do the same thing every time you see them. What a world, huh?

In theory it sucks that you can't just walk up to all your faves and start up a conversation without paying for something first, but it's also important to remember that a lot of talent — especially geekier talent who go to a lot of cons and don't make as much money as superhero movie A-listers — are charging to offset the costs of being at conventions in the fist place. Wil Wheaton said as much in a recent blog post on his website

"I’ve always tried to keep autograph fees minimal or eliminate them entirely, but the reality is time I spend at a con is time I can’t spend working on 'Tabletop,' my books, or any of the other projects I have in development."

True, some celebs don't have to charge for autographs and do anyway, which is a bummer. But you can't know that from your position, so chewing out somebody who doesn't want to sign your book for free isn't fair. Especially if you do it right in front of their face, because you're probably going to ruin it for everybody who has to meet the celebrity after you and were all perfectly happy to pay for that celebrity's time. 

DON'T: Ask them the same question they probably hear all the time.

The media is just as guilty of this as fans are, of course (hey, some of us are fans, too!) but in general you should be mindful of the big topic du jour within your fandom and try to steer clear of it. For example, if you bumped into Kit Harington before the beginning of last season of "Game of Thrones," asking him if Jon Snow was really dead would have been really annoying for the guy. Unless you were a cop who could get him out of a ticket, of course. Then you're just helping him out, right?

Same thing goes with catchphrases. You know how Jon Snow knows nothing? Yeah, so does Harington. Cool it with that, maybe. 

DON'T: Be critical of something they've done.

You'd hate it if somebody came up to you and was like, "Hey, I love your work, but remember that one time you spilled coffee all over your shirt? What was that about?" or even worse, "Hey, you know that job you did that you're really proud of? It was overrated." That's just rude. So don't do that to famous people, either.

DON'T Ask them what you know them from.

Having someone walk up to you and demand you tell them why you're famous has got to be the worst experience ever. If you see somebody you recognize but can't place them in your brain, better just to leave them alone. Odds are you're not that interested in talking to them anyway other than to say you talked to a celebrity, right? 

DO: Be cool if they aren't interested in talking with you.

You don't owe anybody your time, so why should a famous person owe you theirs? If you encounter a celebrity in the wild, far away from their autograph table, and your hero says she's busy when you ask her for a pic, respect that — even if it doesn't seem like she is. 

If you're paying for the chance to speak with the celebrity in question, their disinterest can be much more disheartening. But even though you had a terrible experience, at the end of the day you don't know whether the celebrity is terrible as a person, or if she just had a really bad day during that convention. Try to be as sympathetic as you can, and if you're really worried about having a bad time, research ahead to see what other fans have said about the person you want to meet just in case.

DEFINITELY NEVER EVER: Objectify them.

A lot of celebrities are hotter than we are. That still doesn't give you the right to yell "Lookin' good!" at them as they walk by — that is, unless, it's Eddie Murphy and you are specifically quoting the "Lookin' Good, Billy Ray!" line from "Trading Places" at him. Even then, he probably gets that a lot, so see the above suggestion about not saying the same thing that people always say to celebs and reassess.

Seriously, though, don't say anything to a celebrity that would make you uncomfortable if someone you didn't know said it to you. At best, you are making everything awkward; at worst, you are sexually harassing a stranger. Be cool, guys.

DO: Let them know how much they mean to you

OK, so the moment has arrived. You're in front of your favorite, favorite celebrity in the entire world. Watching this person's work on TV or reading it in their comics or playing their games inspired you more than words can possibly express. But that doesn't mean you shouldn't try to express them.

If you find yourself at a conversation with someone you really admire, there's no point in pretending you're not a huge fan and that they didn't have an impact on your life. If hearing about Jared Padalecki's battle with depression, for example, helped you get through your own dark time, don't be afraid to tell him that if you find yourself standing in front of his autograph table. Everyone likes to hear that they've made a difference in someone else's life, no matter how cheesy or dorky you might think it sounds. Trust me, they'll be happy to know they had such an impact on you.
