Oh good I am not the only one! My DH is adamant about one use towels, I don't mind using the one from my hair on me the next time, though It is often for the kids next time, they don't mind at all, and I know where it has been. Actually I usually use a robe and then I don't need a big towel for me. And I know where the whole thing has been

.
Oh and the hand towels get replaced once or twice a day. The one from yesterday is used to wipe down the sink today, and the one my DH usues on his hair is used for my DSs hair then washed. (curly hair, gets soaked every morning to defrizz it.)
