Puzzle never complained, because he knew that Shift was far cleverer than himself and he thought it was very kind of Shift to be friends with him at all. And if ever Puzzle did try to argue about anything, Shift would always say, “Now, Puzzle, I understand what needs to be done better than you. You know you’re not clever, Puzzle.” And Puzzle always said, “No, Shift. It‘s quite true. I’m not clever.” Then he would sigh and do whatever Shift had said.
