This is all too familiar to me, but from the teacher's point of view. We used to schedule parents each half hour for over a week. Sometimes I would have a schedule like this: 3, 3:30, 4:00, clear, clear, clear, and then 7:00, and 7:00 would not show up. I loved parents like you.
Ooooh, brings back memories of those pesky lockers while in school. Was always afraid I wouldn't be able to open the lock and wouldn't get to class on time. I think I worried way too much!
