“ The apartment is a laboratory in which we conduct experiments, perform research on each other. We discover Henry hates it when I absentmindedly click my spoon against my teeth while reading the paper at breakfast. We agree that it is okay for me to listen to Joni Mitchell and it is okay for Henry to listen to the Shaggs as long as the other person isn't around. We figure out that Henry should do all the cooking and I should be in charge of laundry and neither of us is willing to vacuum so we hire a cleaning service. ”
