Don't Fidget Children

Before they were to attend a cousin's high school graduation, the pastor, knowing how fidgety both of his children can get, thought he'd prepare the two of them for the event. 
"Graduations are sometimes long and boring," he said. "I want you guys to behave and not constantly ask when it's going to be over." 
"Don't worry, Dad. We'll live," the daughter replied. "We last through all your sermons, don't we?"
