Even worse than the fridge is the front door. It was 19 degrees here today, you would think that my kids would remember to shut the door, nope. You know how they have cards that sing a song or give you a message each time it is opened? I'm thinking I need some sort of device like that installed on my front door. Each time it is opened, a recording of my voice saying "Please shut the door!" would play. Now that is a money saving tip right there.
