I fairly regularly commute (3x a week when I can,) same route every time. I had to take a week off (work-related travel.) Next time I was riding into work, car pulled up alongside and the driver rolled down the window. I'm thinking "Ohh boy, here it comes..."
I was shocked to hear "Hey, I didn't see you all last week! Everything OK?" I managed to say "Yeah, fine. I was out of town."
"Okay, cool! Have a nice day!"
I surely did....
