I think this is great. Mind you, it's a pretty extreme form of manners and respect, but even if they take just a bit of it with them I imagine they'll still be head and shoulders above the rest.
I would love for a man to show these efforts with me, it lets me know he respects me. Or at least digs me enough to do so. But when I let him know he doesn't have to stand up everytime I do, he respects that, too.
Of course, we gals should also return the favor. We haz special ways to let them know we dig them as well. Make them feel like a man and such.
