(I have some sort of facial dyslexia, I think. For the first year of school I could only recognise people by their clothes, and they were inconsiderate enough to *wear different clothes every day*! Gah!)

I am moderately good at forgetting people's faces too. Plus I'm terrible with names (both remembering them and, in some cases, pronouncing them). It was a problem at work, someone would come up to me and start chatting as though they'd known me all their/my working life and I'd be thinking Who the **** are you anyway ?.
