For me, it's a hard question to answer. If what you are asking is whether or not I am shy about approaching people to talk to them, nope! Do I spend a lot of time talking to people individually? Yep!
However, when other people are talking, I go into shutdown. People say, "Are you okay, Pudding? You're usually so talkative?" and I reply, "Well, you guys were talking, and I was listening!" and they're like, "Oh, that's weird. You're always just going and going," and I say, "Well, I sort of wish other people would fill in the silences more. It's exhausting," and they're like, "What's wrong with just silence?" and I say, "Because people start thinking I'm weird, and that makes them annoying," and they say, "We already think you're weird," and I say, "No, you KNOW I'm weird rather than thinking it, which makes you more manageable."
I also tend to preserve a handful of close relationships. I'm not one of those people who can say, "Yes, I've got a lot of little friends!" Nope, just me and my partner, trying to survive in the big, bad world.
I also cope very well with being alone for long periods.
