My daughter Michelle is the commander of a Coast Guard Cutter. When she gave my husband Bob a tour of her ship, he was impressed by the neatness of all decks.

However, when Bob went to Michelle's house with her, he couldn't believe the disorganization. "Why is everything in its place on your ship," he asked, "but your house is such a mess?"   

"My house," Michelle said, "does not take 30-degree rolls."
