The Law of Propinquity

No matter how large the parking lot, no matter how few vehicles are in it, and no matter how far away from the store and from everyone else you park... when you come back to your car, you will find that someone has parked right next to you.

Try it next time you go shopping. In a parking lot large enough to hold 200 vehicles, with only half a dozen vehicles in the entire parking lot... park at the far distant end, no other car within six or eight parking spaces of you... and see if you don't end up, in short order, with someone parked right alongside you, so close that they can hardly open their door without putting a ding in the side of your car.

I have never understood the why or wherefore of this law. But it never fails.
