GF got on wrong bus.
Seems that cell phones distract bus riders as much as car drivers...she didn't realize it until the bus was three miles away from the normal route.
Grabbed her car, tossed my bike in the back, and picked her up. She went to work and made it on-time, I got a surprise 4 mile sprint workout in the heat trying to make it back to my home office before anybody at the office tried to instant message me.
Thinking afterwards, perfect use of a bike. Walking back would have taken too long, if she drove me back she would have been late, and the bus schedule would have had me waiting twenty minutes.
