TV
Most people who go on any "reality" Tv show want to be on tv. They want to become famous. Most of these "people" have no real desire to have any real talent, it's just to become famous.
And it's tv... It's all about drama... SOme people who have SA might get through something like this if it's not in the extreme sense.
But at the end of the day, TV is all about drama. So there will be fights, arguments, overacting, and everything else under the sun..............
Plus half these shows provide tons of alcohol.. For the most part, Drunk people are a lot more entertaining then boring sober ones. And it's TV..
Most people who will be "PICKED" to go on these shows will claim to have had "SA" or claim they were once "SHY" but the truth is, if you're willing to go on some Reality TV Show where you will be embarrassed by your actions and inactions, you probably don't have SA.
