"He says it was a good thing when Tom threw a barrel stave in the Chinese laundry because it led to his being a scout. But that isn't logic. Do you know what logic is?"
Mary thought she had a notion of what it was.
"A thing that's bad can't be good, can it?" Pee-wee persisted. "Suppose you should hit me with a brick——"
"I wouldn't think of doing such a thing!"
"But suppose you did. And suppose the scouts came along and gave me first aid and after that I became a scout. Could you say you did me a good turn by hitting me with a brick because that way I got to be a scout? Roy—you got to be careful with him—you can't always tell when he's jollying."
Mary looked at him intently for a few seconds. "Well, then," said she, "since you've made a study of good turns tell me this. If Roy and Tom were to ask you to go with them on their long hike, would that be a good turn?"
"Sure it would, because it would have a sacrifice in it, don't you see?"
"How?"
"Because they'd do it just to please me—they wouldn't really want me."
"Well," she laughed, "Roy's good at making sacrifices."
