Actually, it could go either way with the punctuality. My mom was late ALL the time. Me? I'd rather be 15 minutes early than 15 minutes late - or even right on time. My husband's parents are always late. And he's okay with it. Well, he hates that his parents are always late (when they tell us they'll be leaving in a few minutes, we wait about 20 before leaving our own house to meet up with them), but he's fine with being late himself. Luckily, I mind more than he doesn't care, so we tend to be early for most things.
