I think social interaction is very neccisery for mental health, thats probly why the worst punishment in prison is to be put in the isolation cell, away from all the murders and rapists, and thats the worst punishment. Just shows you something about humanitys inate need for other people I think. I have a fairly laid back personality though, so so long as I'm around people, I'm happy to not be the "outgoing" one. I figure just because I have social anxiety, doesnt mean I need to spend my entire life trying to achive the polar opposite.
