Things Not to Do at Your Girlfriends Parents House Over Christmas

My ongoing list of things I've done wrong while spending this holiday season at my girlfriends parents house.
  1. Criticize the mothers taste in music
  2. Bring up the fact Bruce Springstein could have been my father
  3. Sleep in until noon in their daughters bed
  4. Eat the last of the eggs
  5. Forget to fill up the tank after using the family car
