In my life, I'm HORRID at keeping in touch with people. I HATE the Phone. (though if we had internets back then it may have been a very different story). It tended to be like, if I saw people at like, say, school, I'd only be in contact with them as long as I attended the same school. I changed schools a couple of times so each time I did so, I lost track of the people in the other school.
There was one girl who was a really good friend in Kindergarten and Grade 1. I sorta lost track of her after Grade 2, although there was one time we went skating together while I was at the other school.
Everybody else, I didn't phone (and they didn't call me, but I never phoned them anyway to begin with) and got out of touch.
It wasn't deliberate. I just didn't like talking on the phone.
I've seen some posts that basically detailed how other people with AS also lost touch with others. So it's interesting that I'm not the only one.
Thing is, when High School rolled around, a lot of the kids I considered at least friendly (if not actual friends--I was wary) grew farther apart from me, including the old friend from childhood. She started hanging out with two girls that were cold as ice and distant. And a boy. And given my experience with boys, I didn't dare stick around that.
I HATE it when people feel they have to choose between different people, i.e. can haz one, but then can not has the other one. What a bunch of BS.
