The worst is when your wife says "Don't get me anything for Xmas." Being a man, you take this literally. But you're not totally stupid. So a week later, you say "Just confirming we are not getting each other anything for Xmas." So she looks at you like you are, in fact, totally stupid. "Well," she says, "I think gift giving is an integral part of the holiday spirit," as you sink into the floor.
