Dear Mary: Should I return my pod coffee maker on moral grounds?

Q. I adore doing jigsaws and these days there’s an added bonus — by posting my progress on Instagram I can share the happy glow it gives me knowing that I’m reducing toxic screen-time habits. Recently I begged to borrow a magnificent 1,000-piece puzzle from a friend — a vast winter scene by Pieter Bruegel. Setting to, I succumbed to the meditative calm and satisfaction of puzzling. After two weeks of hard graft neglecting pretty much all domestic duties, the puzzle was finished, but with a piece missing! This maddening lost piece is an obscure blob of twiggy branch that nobody could love, but its absence mocks all my efforts.
