Cathy Jamison wants a pool in her backyard. In fact Cathy has always wanted a pool in her backyard, but she wanted other things more. She got the things and now she's back to wanting a pool. The contractor is not sold on Cathy's pool, and when he explains the facts to her, she apologizes for how small her backyard is. He calls her attention to the shade tree, but she doesn't want that anymore either: She wants sun. Summer in Minneapolis doesn't last very long; this is the first day of summer in Minneapolis.
The contractor talks her into a deck, with a nice sunken hot tub and maybe a barbecue pit. He knows what he's talking about, so Cathy gives in: We'll do a hot tub, even if it costs double because she's skipping in line with the contractor. It's not exactly what she wanted, so Cathy changes what she wanted, on the surface. She is angry with herself for doing it and sad about the pool, but changing her mind is the sensible thing and then, if there is a problem Cathy can throw money at it until it goes away. Cathy Jamison is no stranger to compromise. She is, however, learning about the alternatives.
Paul's been sleeping on his sister's couch, for example; he appears singing the jingle for the pool contractor and making jokes about adultery. Paul is very confused about where Cathy has gone, why she is getting a hot tub in their backyard and where she is going. Paul has a huge knot in his back from sleeping on that couch. He doesn't take things very seriously, although he tries; there is no amount of joking around that could help this knot in his back from sleeping on the couch.
This is Paul's idea of a joke: "I thought we were saving for new closet systems. Catherine, I don't know who you are anymore!" It is also Paul's idea of an insult.
Cathy rubs the knot in her husband's back, which she put there, and Paul is grateful as a hound. One leg almost whisking the air. "Oh, get in there. Oh, honey, can we please fix this? I miss you so much. And I'm so sorry about what happened." (What happened is not the problem, but Paul can't know that; what happened could never be the problem because what happened was just Paul.) Cathy dodges him for another appointment with the dermatologist, who is not actually a dermatologist, which is really the problem. She married her husband because he was childlike. There was an innocence that she loved. Now she is fierce about protecting it; now she resents it because it must be protected.
