I'm a police officer and occasionally park my cruiser in residential areas to watch for speeders. One Sunday morning I was staked out in a driveway, when I saw a large dog trot up to my car. He stopped and sat just out of arm's reach. No matter how much I tried to coax him to come for a pat on the head, he refused to budge. After a while I decided to move to another location. I pulled out of the driveway, looked back and learned the reason for the dog's stubbornness. He quickly picked up the newspaper I had been parked on and dutifully ran back to his master.
