One year, Rivkah decreed that she was no longer going to remind her children of their thank-you note duties.
As a result, their Bubbie 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 Bubbie 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. "I haven’t signed the checks yet."
