I was a really reclusive child.
I didn't really have any OCD, other than the fact that I had to smell all my food before I ate it. But I still do that.
And even though I hated other children, I loved taking our dog for a walk down to this park a few blocks from our house, I'd tie him up on the pole by the swing, and I'd sit there for hours watching the other kids play.
That was my favorite passtime, watching other children play.
