Some of it could be that school is more structured and teachers are giving specific instructions like "Turn in your homework now." She sees everyone else doing it and does it as well. I can never figure out how DD makes it out to carpool on time (most days) when I can't get her out the door in the morning. But if everyone else is leaving the classroom, leaving the locker bay, etc. that is her cue that she is supposed to do those things too. I also found out that her friends were giving her reminders, for instance telling her to go to her cello lesson, reminding her to get up and go to math at a certain time, etc. When she got in a temporary fight with some of these girls then she started forgetting things and it was because she was avoiding them and they were avoiding her, so there was no one to remind her. People w/ ADHD seem to do best when they are surrounded by people who are highly organized (which I am not).
