"I have a problem... Every time I step outside, my feet get wet."

"Hello, blacksmith support... Yes, I see... Have you tried reshoeing it?... OK... OK, double-click on the horse and tell me how many legs it's got... Yeah, that type does tend to fall over. We're working on a fix. In the meantime, please use a peasant."
Being a mum/housewife? No real change there, except then I'd have no human rights.
