If you plan on going to a convention with celebrity appearances, please compartmentalize this. 

Guys, please understand that when you go to a convention - whether it be an "adult film" convention or maybe something like a comic con - and there are celebrities in attendance, please understand that when you interact with them you are interacting with a persona, not the real person underneath. This video explains what happened to me at a recent convention and what I learned and you can learn from it.
