I have decided that my roommates are really good actresses. Every time my boyfriend and I order a pizza, they hang around seeming entirely innocent. Then I come to find out that they've eaten their "fair share" of the slices. They know how much it annoys me (not really that much, but it's fun to exaggerate) and get more and more creative at how they will pull off the stunt no matter how protective of the pizza we try to be. they get the biggest kick out of themselves and their abilities. I guess they are kinda funny...
