In late 2004, I was working in my office, minding my own business. I normally keep my door open, as do most other people.
I turn around. There's somebody at the door.
"Oh, nothing," the person said. "I just wanted to look at you."
I closed the door and drew my blinds.
What would you have done?
(In retrospect, I obviously should have installed a webcam and charged a membership fee.)
