I Cause Marital Conflict

So I'm walking across the parking lot of our condo in Chatham and a lady riding by in a BMW stops her car and says to me (in her Boston accent) "Didja heah my cah squeak?" and I did hear her car squeak, so I say that I heard a squeak and so she turns to her husband in the passenger seat, points at him, and says, triumphantly: "See! He heard a squeak," and then a few minutes later I see her driving all alone, slowing down, and then speeding up, listening, and she says to me, "Nobody heahs my squeak."
