A friend of mines ex never really made sense. They both thought that maybe they go to a certain party, but both knew it was too far away and a lot of trouble. So I asked both to hang out. He happily agreed. She was pissed because she didn't want to. She said "but what if I want to go to that party?" He" I thought we agreed that it is not worth the trouble? She "but if I change my mind?" He (having similar discussions with her occasionally): "whatever, do what you want"

She went there out of revenge, had a terrible time, had no place to sleep, spend half a night waiting for a train.

Out of revenge for not stopping her, she got 2 bunnys. He is a rather practical guy, and she knows he will be mad at her for getting a new duty.
