I graduated from high school in 1982.
I don't even
remember anyone from my class except one girl I
should have forgotten. I forgot them so fast that it was a bit embarrassing when I ran into one of the few people who treated me well a few years later. Now I know I have no memory for names OR faces.
I remember a few people I was friendly with from the next class back, but that's all. I maintained no friendships from anyone at that place for more than about 1 year.
Unfortunately, they all remembered
me when I went to an informal reunion last year.

(sigh) I'm darned if I know why.
