I don't mind being in a crowd now and then so long as it's not for an extended period of time. And if it is, then I'd like to have a close friend with me...security purposes.
Something like this prison would have me all thrown out of whack. They'd send me to a mental ward on the condition they found me in the fetal position with a pillow over my head and singing at the top of my lungs just to drown out the noise. I can deal with crowds, but over such a long period of time, I would seriously go bonkers.
...some of the stuff these guys do, though, is pretty nifty.
That would be tough.
But it seems like if you are a prisoner who doesn't want to be bothered by other people, they won't bother you. I don't know if that makes things a little better for the 'uber-introvert'.
