Cooked a large pizza for lunch. Cut it in to 4 pieces - 2 each for DH and I. He eats his two slices. I eat one slice, then realise I can't eat my 2nd slice, so offer to get the pizza cutter and divide my 2nd slice between us. DH says not to bother getting the cutter, and then picks up the pizza and tears it in half with his hands. He has a sniffly cold, and didn't wash his hands before lunch. I now don't want any of it. He says IABU. Am I?
