"But have you noticed the slight curl at the end of Sam II's mouth, when he looks at you? It means that he didn't want you to name him Sam II, for one thing, and for two other things it means that he has a sawed-off in his left pants leg, and a baling hook in his right pants leg, and is ready to kill you with either of them, given the opportunity. The father is taken aback. What he usually says, in such a confrontation, is "I changed your diapers for you, little snot." This is not the right thing to say. First, it is not true (mothers change nine diapers out of ten), and second it reminds Sam II of what he is mad about. He is mad about being small when you were big, but no, that's not it, he is mad about being helpless when you were powerful, but no, not that either, he is mad about being contingent when you were necessary, not quite it, he is insane because when he loved you, you didn't notice."
