Walking after dark tonight, through a parking lot, I was puzzled by the distinctive thunk of someone's automatic doors being locked. (About thirty feet away from me - it seems a car towards which I was coincidentally walking housed a lady on her cellphone.)

I don't know whether to shake my head at the feeble judgment of my neighbor, or to smile at the thought of me developing enough personal presence that my most pedestrian acts can serve as a call to action.

Seriously, who locks the door when they see me coming?
