Personal Thank You

One year, a Mother 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 for their birthdays.

The next year things were different, however.

"The children came over in person to thank me," the Grandmother 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."
