I don't know the man in the car in front of me. We have a relationship, though. He puts his left turn signal on for me. He maintains speed on the turn so as not to cause me to slow down. I am in his rearview mirror.
When we reach the end of the on-ramp, he maneuvers onto the freeway, still maintaining speed, deftly fitting between two cars.
He has not inconvenienced me. I wish all my relationships were so successful.
