Q. My spouse and I actually had a rare, big fight over the utterly ridiculous question of how often one should change bed sheets. I say every few days so they feel nice; he says that wastes water and energy. Who is right? — Likes a crisp bed

Dear Crisp: You are both right. There is nothing like nodding off between clean sheets, and it does indeed take water and energy to get them that way. Consider going a day or two longer between changes, then washing in cold water and hanging sheets to dry, which saves energy and makes them even more crisp. Before you fall asleep on said sheets, you might also consider sending up a prayer of thanks that this is what counts as a big fight in your house.
