One night a few years ago, I heard a siren, went to see where they were going, and they were coming here. A police officer and a fireman had already gone around the house into the back yard and another police officer was at the front door.
With caller ID on the phones now, it didn't take long for them to find an 11 year old girl at the other end of the block had called 911 and reported a fire at the back of the house at our address. We'd never met her or her parents, and she'd just picked a house number at random and did it as a prank with a friend visiting that night. She, too, sent us, the police department, and the fire department letters of apology, as well as her parents making her come to apologize to us in person.
