Later, lying in bed, I wonder if Dena knows about her father. I decide that she probably does, and I imagine how I would feel if I knew that my father was unfaithful to my mother.
Then I remember Richard, and I think that marriage might not mean much to Dena. I can't really blame her: She learned about marriage from her parents, just as I did from mine. For all I know, sleeping with Richard is just Dena's way of trying not to be her mother.
