"The mester wud punish us," said another girl.
"But," I cried, "surely one of you has thrown things about the room?"
Tom Murray, the bad boy of the school (according to Mac), put up his hand.
"Please, sir, I did it once, but the mester licked me."
"Why did you do it, Tom?"
Tom thought hard.
"I didna like the lesson," he said simply.
I then went on further.
"Now I want you all to think this out: was Tom being selfish when he threw paper, or was he unselfish?"
Everyone, Tom included, judged that the paper-throwing was a selfish act.
