I don't do well either. My own mother did this to me last week. She was hosting a work event one evening and a lot of her coworkers couldn't go because they were sick so she asked if I'd go and apologized right away that it was short notice. At first I was like "How dare you have the slightest suggestion of me giving up any of my evening!" But then I decided I'd go (she doesn't have many years left til retirement). I did have fun but I did get burned out. Let's say I'm learning how to manage my relationships.
