A colleague of mine related an incident in her neighbourhood that happened recently.
The story begins when a couple decides one weekend afternoon to start up their barbeque to make dinner. They go out to the back yard, only to realize that their barbeque is no longer there. They figure it's gone for good, and since it wasn't brand new, nor was it especially valuable and they were in the market for a new one, they didn't bother to report the incident to the police or their insurance company.
A few days go by, and the homeowner is mowing his grass and goes round to the back yard again, and finds his barbeque has been returned. There is an envelope attached. He opens the envelope and finds a note inside to the effect that "Thanks for the use of the barbeque, you weren't home when we called to borrow it and we were having company over and didn't think you'd mind. Hope we didn't inconvenience you too much. Here are some tickets for the next football game. Enjoy!"
The homeowner was very excited about this kind gesture, and naturally took advantage of the offer of the football tickets. Unfortunately, when they returned from the football game, they figured out that they had been set up: Their house was robbed clean during the time they had been at the football game.
