DEXTER: You know, before I got married, Emily used to come by sometimes and help me clean out my apartment. Well, I asked her, “How come you’re so eager to help clean up my place when your place is just as bad?” She said, “Because cleaning up your place helps me to forget what a mess I’ve made of mine, and — when I sweep my floor, all I’ve done is sweep my floor. But, when I help you clean up your place, I am helping you.”
