A teacher in one of the primary grades of the public school had noticed a striking platonic friendship that existed between Tommy and little Mary, two of her pupils.
Tommy was a bright enough youngster, but he wasn't disposed to prosecute his studies with much energy, and his teacher said that unless he stirred himself before the end of the year he wouldn't be promoted.
"You must study harder," she told him, "or you won't pass. How would you like to stay back in this class another year and have little Mary go ahead of you?"
"Ah," said Tommy. "I guess there'll be other little Marys."
