When we live with people, it’s easy to take their presence for granted. Bonding and communication are effortless. We update each other on our lives while toasting bagels for breakfast and recap the day during evening dish duty. The people we live with know about the good book we’re reading and the tooth that’s been bothering us for the past couple days. They tag along to the movie we’re seeing and show up to our hockey game because we mentioned it last week. Housemates are intimately involved in each other’s lives by association, with minimal effort from either side.
