Okay, so the Younger Daughter was washing the dog last night in the bathtub. In the middle of the bath, she came out carrying the dog and heading for the kitchen. When I asked what she was doing, she informed me that the hot water had run out in the bathroom, so she was moving to the kitchen sink. Should I be worried about the lack of common sense? Then again, maybe you don’t know until you think it through that each faucet does not have its own hot water supply.
