My wife has said many times, to me and others, that she thinks I have a form of face blindness.

I wonder about myself sometimes.

I have a really hard time recognizing someone if the context changes unless I know them fairly intimately. If I see someone I work with every day at the grocery store I will have no problem recognizing them. If I see someone who I wave to in the building when we pass, but who I rarely if ever interact with, I will really struggle to notice that it's someone I know. I've run into my son's teachers (who I generally at least see every day during the school year even if we don't interact) and had 30 secs of panic before I could click into place who I was talking to.
