I drove out of a c-stop parking lot once and forgot to turn my lights on. On “Devil’s Night.” In front of a State Police cruiser. Who was the husband of the Den Mother I worked with. With about 20 lbs of toilet paper that we’d just bought. We all had a good laugh when the “serious” part of the stop was finished. I even straightened out the hood ornament on the cruiser (to the shock of the other guys that were in the car with me). One of the troopers laughed and said it happens every time they would run it through the car wash.
For his replacement car (if/when he ever gets one) make sure his headlights are on automatic so they turn on at dusk and off after sunrise (and turn on when the wipers are on). I know he won’t be driving so much at night, but that way he can’t forget to turn them on.
