New rule in my house

I've had enough. From now on I'm leaving the toilet seat up, and I'll go as far as telling my wife that she must put it up after use too.
Am I being a male chauvenist pig? Nope! Just happen to be parent of a 3 year old who is learning to do stand up peeing, and if the seat is down he doesn't put it up before he goes, resulting in a wet seat that needs cleaning,a wet floor that needs mopping and a wet rug that needs washing!
