I left a carved pumpkin outside our front door and tonight some kids stole it and kicked it down the street. It was the one I did; the kids' pumpkins are safe inside. A few years back, someone stole a very nice Christmas wreath off our front door that Jenny had spent a lot of time making.
We live in a pretty good neighbourhood but you often get groups of kids walking along the street. There's plenty of pranksters. It's quite sad that these things happen and makes you think twice about putting up decorations.
