What i would do would be to simply give them the gift of you NOT breaking into their house, and stealing all their stuff. Imagine the stress, unpleasantness and the feeling of being violated that you would save them?
Surely that would be a great gift?
But how would they ever know about it then, I hear you ask?
simple.
Just break into and rob the two houses either side of them, and they will feel really lucky that it wasn't them
Simple and straightforward, and it wont cost you a penny. Xmas sorted !
