The one thing that does seem to distinguish Mr. Smith from his counterpart is his love of disagreeing with his wife. It really does seem to be his favorite pastime. Often he seems to contradict her just to be contradictory, rather than because he has a strong opinion about anything. He often even contradicts himself immediately after expressing a certain opinion. The one time he really sticks to his guns is during the great doorbell debate. Mrs. Smith becomes convinced every time the doorbell rings no one is there. Her husband is determined to refute this theory, and argues that, to the contrary, every time the doorbell rings someone is indeed there.
