Jane, I don't know. One year when I was in University I had a choir performance for Christmas I was very excited about. I accidentally overslept and called my mother at work crying because there wasn't enough time to take public transit. She left work, came and drove me, I sang in the choir and never have forgotten her help. Sometimes we act irresponsibly and the very thing that makes us better humans is to have someone save us. My mother's kindness and support made me a better person and parent. If he truly forgot and didn't get lazy, I may have gone back for it. But I understand the choice you made.
