So I do the only thing I can do. I walk over, shut off the music, and say to the entire room, “I have a rare neurological disorder called prosopagnosia, which means I can’t recognize faces. I can see your face, but as soon as I look away from it, I forget it. If I’m trying to think of what you look like, I can’t conjure an image, and the next time I see you it’ll be like I’ve never seen you before.”
