One of them is the fact that I came home from work one day to find the front door to my apartment standing wide open with no sign of break-in and my computer screen, television and CD player missing only to reappear again two days later neatly stacked in front of my front door early in the morning. But most of my experience has been far less... tangible.
Since most burglaries, statistically, are committed by a 17 year old boy that lives within three blocks of you; wouldn't the most logical conclusion be that his parents caught him and made him return the stuff?...or he's working his 12 step program and was trying to right a wrong?

But anyway, whatever the answers are man. Don't let the World drive you batshit. It has just as many good things in it too.
