Harry and his neighbor Joe often borrowed things from each other. One day, Harry asked to borrow Joe’s ladder. Joe said, “Sorry, Harry, I’ve lent it to my son.”
Remembering an old saying that his grandma often used to tell him, Harry said, “Joe, you should never lend anything to your children because you’ll never get it back.”
Joe replied, “Don’t worry, it’s not my ladder. It’s my dad’s.”
