I've had two black friends in my life.
One, was this super skinny kid with huge glasses. He was very friendly. But he bit people. Like, spontaneously something would snap in his mind and he'd become some sort of homing missile that had to bite someone to restore his sanity. He moved when I was 10.
The other was a pretty normal guy (former bully, but I beat his ass into stopping that crap) who was very chill and liked the same shows as I did. As such, I'm certain he must have grown up to be a huge weeb. But I haven't seen him since I was 14.
