D15 is STILL like this (and a soph in high school now!). She does have a non-verbal learning disability, so maybe this is part of that. She wasn't sure which set of grandparents was which (we saw them 3-4 times a year when she was small) for years. And she can't tell me which kids are in her classes (small school, ~75/graduating class) even a whole quarter into the year except a few of her good friends.
