Harry and his neighbor Joe oft...
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 a 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."
