Our minds are wondrous things, aren't they? As far as I know, I don't have a brain injury, but I have always had trouble recognizing familiar faces...when I see them out of normal context.

Throwing an auditory note in--I haven't yet managed to teach Hubby that at least 75% of the time he doesn't have to raise his voice after I say, "What?". It isn't that I haven't heard that he's speaking: it's that he hasn't gotten my attention off of whatever I've been focusing on before he says what he wanted me to hear. I did teach the kids, though, to say Mom?, and that then when I was looking at them I was going to take in what they were saying.
