R sits at home, alone, dejected. She is waiting for L to come home so that he can pay attention to her, entertain her. But when he arrives he begins to talk about work. "I wish I could figure out how to do this thing!", he says. " Are you interested in hearing about it?" Out of a sense of duty, R nods. "Mmm-hmm." "Well, There's the one way of doing it which is just an approximation, but a pretty good approximation and I've got it working that way, but when you try to do something more complicated, it breaks down. So what I've got to do is...blah, blah, blah" R is tuning him out, disappointed and bored. She stands behind L and wraps her arms around him, kissing the top of his head. "Keep talking," she says, "I'm listening."
