I got a call from the school number and was all panicked...until I realized it was the school librarian for my kindergarten kid who was calling to tell me that my son had not returned his library books and would not be able to check out another book (it will be "on hold") until his now-overdue books are returned. I was like WTF?? Anyway, I feel like this is why its so hard to be a working mom. Because there are things / systems like this. I get she was just trying to enforce the school's rules but I mean, even as a adult, if I were to borrow a book it would become overdue now and again. I wish they'd just charge a fine than make me feel like this / take my mental energy in this direction.
