Dancing with the Universe

Every time I wash my car, my dad wanders out and quips, "Wanna wash my truck, too?" He's trying to be funny, and every time it annoys me out of (it feels like) all proportion. Today I finally got my courage up and told him that while I know the comment is meant to be amusing, it's actually kind of offensive to someone with Chronic Fatigue Syndrome.

I know he wasn't trying to offend (and said so). He apologized and that was that. I spent some time trying to figure out why it's offensive, and got a few answers, but not as complete as I'd like. I'm notoriously bad at this sort of thing.
