Maggiemaybe, we subscribe to If it's yellow, let it mellow, If it's brown, flush it down, and I'm not embarrassed to admit it. We are on a water meter and try to save water as much as possible.
My DH told me once that he noticed a friend of his had not washed his hands and said "Didn't your mother teach you to wash your hands after using the toilet?" to which he replied, "No, but she did teach me not to pee on my hands". Since urine is sterile when it leaves the body I sometimes wonder whether he had the right attitude, although I do always wash mine. I don't leave the tap running though.
