You all look the same to me.
I suck at recognizing people. Seriously, I've got a problem. Case in point: a while back, me and the Fawning A. were watching some film on the telly, and I go "Heyyyy, I know that guy. He's been in loads of stuff. What's his name?"
The Fawning A. turns to me with a look of utter incomprehension and says "Dude. That's Robert Redford."
And I wish that was abnormal for me, but sadly it's not. I am so crap at recognising people it's untrue. Faces are not only unhelpful to me, they can actually throw me for a loop-- I can sometimes recognise someone better if I don't see hir face. See, it's not a pattern recognition thing. I recognise patterns fine-- probably better than you lot. It's just human faces that throw me.
Just as a for example, I was watching Buffy videos yesterday and was able to spot that the guy playing the demon with the horns and the beard and stuff was the same guy who played Clem, the demon with the floppy ears and the saggy skin. That sort of thing happens a lot. When the face is occluded with all latex and yak hair or whatever, I'm free to look for other cues-- voice, intonation, body language.
So I'm better at recognising demons than people. I'm comfortable with that. Most people are really boring looking. If you hom. saps. would just make a bit of an effort, I wouldn't even have this problem.
