I'm an introvert.
In some situations I become an extrovert though (such as teaching a class).
But I would always choose a quiet library over a noisy social gathering.
Maybe this is where my son gets his dislike of people from, although to a much greater level.
I particularly hate noise, annoying background music in shops and cafes can make me feel physically ill. Actually I could maybe live alone in a forest like my son, I can see the appeal, I could be a hermit like GoingNorth - although my treehouse would need to have an en-suite bathroom and laundry room - haha.
