After a beautiful purebred puppy wandered onto our back porch and made himself at home, my husband composed an ad for the "Lost and found" column of the local newspaper. It read: "A puppy, male, approximately nine months old, no collar, very friendly, found on Rockbridge Road. " I feared all the detail might encourage an unscrupulous person to claim the dog. As I methodically explained why each clue revealed too much, my husband dutifully crossed out the words. Finally, in frustration, he rewrote the ad, reducing it to a single sentence that I couldn't refute. It read: "Guess what I found?"
