I was putting our flag out yesterday, which was also my wife's birthday. Given that I usually only put it out on holidays (Memorial Day, Armistice Day, Flag Day, etc) my wife asked why. This was the conversation:
Me: "For your birthday"
She: (Gives that "certain look") "No really".
Me: "Because it is May Day".
She: (Looking a little confused) "Is that a flag holiday?"
Me: "It is for communists."
She gave me that "really certain look", shook her head, and I am sure quietly wondered how she ended up with a nut like me.
As I said, my wife is a saint.
