Imagine this:
In a dark night, while you are in the comforts of your home, strangers, wearing costumes that conceal their identity, approach your house, and start heading towards it, trampling your freshly mowed grass and violating your 3rd Amendment Rights. Despite warnings to turn back, and several obstacles in their way they still make it to your house, and begin to bang on your door. You reluctantly open the door, and you are slightly spooked by their outfits. However, instead of leaving, they violently yell at you to give them the food you bought with your hard earned money. After you franticly search your drawers for the food, you hurry them out of the house, and they, carrying their stolen goods in round containers, search for their next victim.

This is Halloween.
