a depressed guitar-playing sysadmin who identifies with marvin the martian... I was like "wait is this my dad?" Well he he retired now.

FWIW he has managed to get old (2x your age) and even though I had a somewhat strange childhood I wouldn't choose a different parent even if I could. A lot of people I know who had "normal" parents suffered a lot at their hands in ways that were not even conceivable to me. He didn't get any kind of therapy til more recently and it has vastly improved things for him and those around him.

I'm one of few in the world who know him and he is one of my favorite people.
