The other day I passed a road construction crew, as one of its workers attempted to alter the traffic pattern from three lanes to two.
The worker was placing large orange traffic cones onto the road, and probably the simplest function he’d perform all day. He easily placed about seven cones diagonally, starting at the right edge of the canceled right lane, to the left edge. This action, obviously, forced drivers in the right lane to move to the middle lane. Interestingly, as he walked away after performing this function, he turned around presumably to review his handiwork … and slightly smiled.
I don’t know what was in his head, but it tells me that it’s human nature to feel satisfaction after a job well done, regardless of its simplicity.
