My twin brother and I shared a room from womb to thirteen-years-old. Those of you who have had a roommate know that you must develop and agree on certain rules to keep the peace. For example, we agreed that the last person to get in bed must turn off the light. Paul was notoriously and egregiously derelict in following this rule. There were several nights when, in our stubbornness, he and I would leave the light on until two or three in the morning because Paul refused to turn out the light under the terms of our agreement. Of course, I would eventually give in, huffing and fuming, and turn off the light.
