A teacher is telling her students the importance of making others glad. "Now, children," she says'Did you make someone else glad?"

"My granny." The boy says.

"Good boy. Now tell us how you made your grandmother glad." The teacher says.

"Well done. Who was that?" The teacher says.

"Please, teacher," says a small boy, "I made someone glad yesterday."

"I went to see her yesterday, and stayed with her for three hours. Then I said to her, 'Granny, I'm going home.' And she said, 'well. I'm glad!'"
