But... that's unnatural. And icky. And stuff. Guys don't do that. Really, would you sit on a toilet seat if you didn't have to? (Especially if not doing so meant that you didn't have to get halfway undressed, too...)

Really, flipping the seat is not a big deal. I'll do it when I need to. But you're a big girl. Why can't you do it, too? Without complaining.
