Operator Error

My Dearest took our boys to the bathroom in a restaurant to wash hands before dinner this evening. They discovered the automatic hand-dryer, which required them to put their hands under in order to turn the unit on. After experimenting and quickly mastering it, one boy noticed there was a paper towel dispenser next to it. This was the type where each sheet was folded into the next, kind of like inverted pop-up tissue or moist towelette dispensers. Our son tugged gently on the paper towel and asked my Dearest, "How do you operate this?" He's such a precious boy.
