"The Itsy Bitsy Spider crawled up the water spout.
Down came the rain, and washed the spider out.
Out came the sun, and dried up all the rain,
And the Itsy Bitsy Spider went up the spout again."

(Henry's father died and Henry had taken care of her mother.)

(When they are in bed:)

Henry's Girlfriend: Ok. For a long time from what you told me, you are always the parent in the relationship.
Henry: Yes.
Henry's Girlfriend: And you doted on your mom because your father had abandoned her.
Henry: Um.
Henry's Girlfriend: And then you became the surrogate husband.
Henry: Okay.
Henry's Girlfriend: So I am just thinking that maybe you are little hung up on your mama.
Henry: Oh, that is disgusting!
Henry's Girlfriend :I don't mean in a sexual way.
Henry: Good, I would hope not.
Henry's Girlfriend: Although … there is a large sexual component to mother/son relationships.
Henry: Oh, God. (turn away to sleep)
Henry's Girlfriend: All right, forget it.
(Silent..)
Henry's Girlfriend: Do you ever think of your mom when we are having sex ?
Henry Jumped up: oh, God!
Henry's Girlfriend: just a question.
