Some people, perhaps, don't "hit their stride" until their twenties, when the growing-up business is over and women appreciate other things besides wisecracks and teasing and strutting. Peter didn't have one-tenth the imagination he had, not one-tenth. Peter did this naming-their-children thing as a joke, making up names like Aloysius and Murgatroyd, but Ambrose knew exactly how it would feel to be married and have children of your own, and be a loving husband and father, and go comfortably to work in the mornings and to bed with your wife at night, and wake up with her there. With a breeze coming through the sash and birds and mockingbirds singing in the Chinese-cigar trees. His eyes watered, there aren't enough ways to say that. He would be quite famous in his line of work. Whether Magda was his wife or not, one evening when he was wise-lined and gray at the temples he'd smile gravely, at a fashionable dinner party, and remind her of his youthful passion. The time they went with his family to Ocean City; the erotic fantasies he used to have about her. How long ago it seemed, and childish! Yet tender, too, n'est-ce pas? Would she have imagined that the world-famous whatever remembered how many strings were on the lyre on the bench beside the girl on the label of the cigar box he'd stared at in the toolshed at age ten while she, age eleven. Even then he had felt wise beyond his years; he'd stroked her hair and said in his deepest voice and correctest English, as to a dear child: "I shall never forget this moment."

The day wore on. You think you're yourself, but there are other persons in you. Ambrose gets hard when Ambrose doesn't want to, and obversely. Ambrose watches them disagree; Ambrose watches him watch. In the funhouse mirror-room you can't see yourself go on forever, because no matter how you stand, your head gets in the way. Even if you had a glass periscope, the image of your eye would cover up the thing you really wanted to see.
...
In a perfect funhouse you'd be able to go only one way...; getting lost would be impossible; the doors and halls would work like minnow traps or the valves in veins.
