I never understood why they dont. is having a weewee somehow stop you from reaching the soap?
no but consider what generation or father's were from. Hell my Grandmother used to iron my dads boxer's, Mom broke him of that habit by starching his shorts.

Growing up every Saturday all the kids had to help clean the house, vac, dust, clean our rooms, clean bathrooms, take out what ever trash hadn't already been taken out. I always got stuck with the "nasty" jobs as mom "knew I would do it right the firs time." Plus the boys had to mow the yard or shovel depending on the season.
My sister got stuck with dusting and polishing the silver if it needed it. But, to this day she still enjoys doing that.
