Autism

"Kids with autism often can't make connections that other kids make easily. For example, when people smile, you know they feel happy or friendly; when people look mad, you can tell by their face or their voice. But many kids who have autism spectrum disorders have trouble understanding what emotions look like and what another person is thinking. They might act in a way that seems unusual, and it can be hard to understand why they're doing it."

In some ways, I do inappropriate things as a reaction.  However, I come here to say that I used to wave and say, "hey," to people in 1997 and 1998 when I was in 6th grade just before moving from Florida to Louisiana.  I had no "good" friends.. but wasn't "unpopular," at all, in a way.
