Situation: A couple, newly together, watches a DVD together. She falls asleep half-way through. The next morning he sends her an email…

“Thank you so much for last night. It is wonderful to have someone who thinks enough of me to watch what I wanted to see. I know you don’t like horror that much. You were obviously very tired. I’m delighted you were comfortable enough with me to fall asleep. I wore the same shirt today because you left a tiny bit of drool on my sleeve and I wanted to keep you close. See you tonight.”

Same couple, same evening, five years later…

“I don’t get you! Not only do you not care about anything I want to watch but you fell asleep on my favorite shirt and drooled all night! Next time, just go to bed. I’ll be home at 7:00.”

Same couple, same evening, 15 years…

“Enjoyed the movie. I dropped off the laundry (I got something on my shirt). Did you take the DVD back? Pick up something else when you go – one of your favorites this time. Oh, I’ll be home at 5:30, do you want to go out for dinner? You pick.”
