Sometimes it's hard to separate what is a legitimate beef and what is just the nutso stuff! The cable thing was really her anxiety about having to take over all the bills after I was gone. Of course, all she needed to do was say "could you help me understand some of these bills I'm going to have to pay?" but that would be demeaning to do, it's much better to be snarky, rude and demanding Go figure!
Go figure!
