When I was a kid we never even locked our doors in our small town. Especially at Christmas. If you locked your doors you wouldn't get the meat pies and fruitcakes delivered to your fridge during the day.

I think most people lock them now. It is still very safe but there has been a small invasion of drugs and thus an increase of the resulting minor brake ins. Sadly Santa might have to use more magic than he used to.

With great power comes Awesome irresponsibility.
