Chomsky's words could be my own, here. I stayed with Daniel there, behind the museum, many times. I walked a lot, but I think maybe I was supposed to attempt speaking with people, in some manner. Not the sort of ghost that I was, drifting in and out, unnoticed, engaging with nothing and no one. Except the food, when I could scrape together enough courage and crumpled bills. New York has some of the best food I've had anywhere, and sometimes it was even pretty cheap.
I couldn't really afford to do much but wander. I did hang out at lots of book stores. Once in a while, even bought one. Sometimes went to see live music at this one tiny punk club I liked. Mostly just did a whole lot of walking though. Even at places and times, I really should have been more nervous than I was.
Doesn't seem exactly like the behaviour of someone overcome with anxiety. An over active fear center would be more generalized, and that doesn't seem to be the case with me.. maybe that's why social anxiety doesn't necessarily feel like anxiety. Maybe biochemically, it is something a little different.
I was fine, as long as I didn't have to interact with anyone - and yet that was possibly the whole point of all that wandering.
