How long can you go without social interaction?
I've never gone a day without social interaction of some sort. For me, it doesn't have to be face to face. I am constantly updating my closest friends (ISTJ and ISFJ) on what I'm thinking/doing over facebook IM as if it were twitter or something. As for hanging out physically, well, all but 2 of my friends have left town for college, so I can go weeks without it. I work in customer service at work so I get a lot of interaction anyway.
How long can you go without alone time?
A day? It depends. With friends it can be longer, but if I'm dealing with people at work or people I'm not partial towards, a day of bieng around them and I need a few hours to recover.
What situations drain you the most--clubs, seminars, a weekend alone, parties, etc?
I don't go to clubs or parties--not my thing. My idea of a "party" is inviting all my introvert friends over for a movie marathon or something (100% of my irl friends are introverted). I don't think I'd like going to block parties or clubs or anything like that.
What energizes you?
Doing things that are FUN and not work. Playing my wii u, either alone or with friends. Browsing this forum, watching tv, hanging out with friends. Anything, as long as it's not going to work!
How long does it take to recover from a draining situation?
Depends on HOW draining it is. It could range from a couple hours to a day.
