Many moons ago, I used to keep a spare key in my ash tray of the car (never used for ashes). I usually didn't lock the car doors at home either. Anyway, one day thieves broke in and stole my key, and left the car!!!!!!
I still don't lock the car, but no more spare keys in the ashtray.
Probably throughout my life, I've had a bit over $1000 worth of mostly tools stolen. The worst is to loose a toolbox, and never know exactly which tools were in it, so one never knows when a particular tool is misplaced, or stolen.
However, I wonder how much of my tax money is going to support the police, judiciary system, and prison system. I have to believe that the government is taking far more money than is justified by my losses.
