The Wager: Short Story

At 12:30 in the am, in the dark of a park, two were driving. One in the passenger seat, contemplating the meaning of success. The both wonder why they cannot be satiated with the amount of success. Both wonder what is missing from their chests.
"Is it money?" One asked the other.
"No. I don't think," said the driver. Though he was right, it seemed like an easy fix. Both knew that was not quite right, and still the contemplated into the night. Though they had written, ridden, and were driven, neither of them had a clue what the secret ingredient was.
"Is it time? Is it space? Is it love?"
"We have an idea of those, so I'm going to have to say no." Though they continued driving and moving on, neither of them had an idea what was going wrong. And as they drove through the zoo, suddenly one of them got a clue.
"Perhaps the best idea, is a friendly wager?"
"What do you propose?"
"We finish everything and become successful, cross every avenue. Turn every stone."
The driver kicked the break and stepped from the car, for once, this was a brilliant idea. Sitting in front of a dead end sign, they knew what had to be done. They put the wager in writing under the rising sun.
"We'll know the loser."
"And the winner."
