On divorce and breaking down of marriage

A ninety three old lady petitions to the court to divorce her 100 year old husband. Could not contain his curiousity, His Lordship asks "Are you sure you want to go through this, considering your age and the fact that you have been together for almost eighty years."

"Yes, My Lord," the old lady replied, "but our marriage had already broken down seventy years ago. In order not to bring any pain to our children, we agreed to divorce only after all our children had passed away."
