The
man who only dated caves would ride his bicycle to work every day. All
the cars hovered high above the ground in 2013—like a sci-fi
film!— so the streets belonged to the bicyclists.
He rode his bike to work, and dinged the bell every time he saw a
fellow rider. The other rider would ding back, and the man felt good
about things because of it.
The other rider dinged. The other rider recognized that the man was a
fellow bike rider. They had this one very significant thing in common.
