I actually went and read part of there post history and

    "My wife lost the diamond in her wedding ring and we were talking about getting it replaced. I have two daughters in their early 20s and they were aghast at the idea..."

I did notice the plurals. If so then I probably get it. That said, High Schoolers, if in their teens do tend to sleep in longer (unless they're those annoying up-with-the-lark types), and can be a bit more self sufficient when trained properly :) so you could knock an hour off that schedule.
