I can't describe the face of my family members to a sketch artist. I mean, I know I can recognize their face if I see it, but I can't take 2 of them and tell you who has a bigger ear, or nose or lips, or if one has a more round or oval face. This is with my own family members I see often. I use to think that people who claimed they could visualize where lying and making it that claim up until a few years ago.
