One Christmas, mom decreed that she was no longer going to remind her children of their thank-you note duties.
As a result, their grandmother never received acknowledgments of the generous checks she had given the children for Christmas.
The next Christmas things were a little different, however.
“The children came over in person to thank me for the generous Christmas gifts” the grandparent told a friend triumphantly.
“How wonderful!” the friend exclaimed. “What do you think caused the change in behavior?”
“Oh, that’s easy,” the grandmother replied. “This year I didn’t sign the checks.”
