Do celebrities get annoyed when you act nervous around them?

[ChelseyEasley]

Okay, I went to a convention earlier today and I got to meet some of my favorite actors and actresses. They were all really nice. I was so nervous. I tried my best not to be but the more I tried the more nervous I got. Especially around one particular actor who I've had a fan girl crush on forever. I was shaking around him at one point. Not bad I don't think, but enough for my friends to notice. And with practically every single person I met I forgot to give my friends the camera for the picture. I would stand beside them, they would put there arm around me then my friends would be like "We need the camera"... to justify myself I just told the actor/actress that I was nervous and they would all smile and say "there's no need to be nervous." I know these actors/actresses won't remember meeting me but I'll remember meeting them. So what I'm asking is, does it annoy or bother celebrities when fans act nervous around them?
