On my walk from the parking lot to the radio station, I pass a guard in a kiosk who controls most vehicle access to the university. It’s pretty lonely and quiet at 5:50 a.m. I used to wave to the guard as I passed, and the guard (one of six or seven people with that job at any given time) would wave back.
These days, I never wave, the guard wouldn’t notice me anyway. The guard’s always looking at his laptop, doubtless immersed in the world wide web or a good computer game. I’m not complaining, I’m sure the guard’s life is less boring than it used to be.
