Nonverbal learning disability: says they can't read people well but I CAN-I just don't know how to respond to ppl. Does this make sense, is it common?

There are no all-or- nothing rules about any learning disorder. Ask the PhD who did your neuropsychological evaluation to explain your strengths & weaknesses in social expertise. You may "get" facial expressions but not be able to modulate the volume, detail or nature of information that a conversational partner wants or needs. The sections on NLD & ADHD on may help you pinpoint areas to work on.
