As much as I really liked the term "Socially Neutral" (lol), I'd have to say that while I can deal with social situations, I don't particularly enjoy them if I'm in a group and don't know anyone.
I was talking to someone about why it's so hard to make friends when you get older. He was saying that when we're younger, we'll do what everyone else is doing to meet people and fit in, even if we're not particularly interested in the activity. As we get older, we're pickier about how we spend our time, and that can result in fewer opportunities to meet people.
I'd have to agree. I am the type of person who can meet 200 people and only feel close with 1 or 2 of them... but then I wind up hanging out with those 1 or 2 people over and over. I prefer a handful of close, trustworthy relationships (the types of friends you can call at 2 AM, would lend you money, or help you pack if you're moving) to having lots of acquaintances, and in my experience, it takes a bit of time and effort to develop friendships like that.
