But, maybe their relationship isn't like yours was. Besides, maybe she was being passive-aggressive about you, rather than him; she knew you would make sure he was up and maybe she resents that, either wishing their relationship was more exclusive or pushing her luck by thinking if AJ has a problem, he'll blame you since you are "in charge" of his getting up in time.

It is small-minded, a bit ugly, but she's young, remember. I think some young people feel they have to make others look bad so they look better; whether it was you or AJ she was aiming at, it was petty but not really worth your fretting over? AJ is responsible for getting himself up on time when all is said and done.

He wasn't late was he? I think if he was working late the bosses won't mind a few minutes late; mine never did after a long period of hard/late work/overtime.
