I'm increasingly convinced that there are two ways of watching television, and that The Wife and I are firmly planted in opposite camps. The first way treats tv as the home equivalent of a movie. You don't start watching until you're ready to focus on it; then, once you start watching, you focus cleanly until the program ends, you lose interest completely, and/or you fall asleep. (In practice, 2 sometimes shades into 3.) The purpose of the DVR is to skip commercials.
