The answer to "Who broke my zipper"

The answer is "Someone (Aka:Dean)". At the old house, the backdoor was where Maddie and I would usually enter. Our jackets were hung right by the backdoor. Weeeeell, one day I was leaving to go to work and her jacket zipper must have moved into the path of the door. When I left I must have have slammed it in the door and broke it. When telling the story of what happened to her jacket, she diplomatically said "someone" rather identifying me as the culprit.
