Woman: Go empty the bucket under the drip in the cellar. It’s half full already.
Man: Okay. [Goes to cellar, gets distracted doing something else, forgets bucket.]
Woman: Did you empty the bucket?
Man: Oh. [Goes into cellar, looks at bucket, which has a centimeter of water at the bottom, goes back upstairs.]
Man: It was nearly empty.
Woman: I thought it was half full.
Man: You always do.
