The Workshop

There are two cars parked in a workshop. Both have a huge dependency on oil. They are both drivable, but constantly have to stop at fuel stations to top up oil. This is costly in time, money and energy. A fairly simple leisurely trip to their favourite holiday stopping point, had now become a tiresome hassle.
So the first car realizes it needs to have it's rings replaced. It's a long process, it hurts and it's very uncomfortable, not to mention messy. But once it's done the little car is no longer dependent on oil to complete it's journey. It's eager to get out of the dirty, smelly workshop and on tho the road into the fresh air. It wants to reach the place where it will be able to stop and enjoy peace.
The second car also realizes it needs its rings to be replaced. But he doesn't really want to go through the hassle. He keeps asking the unprofessional mechanic to just top up the oil it used. It wants to continue on its journey immediately and does not want to wait to be fully repaired. He does not want to take the time.
The two cars continue on their journey, the second constantly forcing the first to stop and wait for it to top up oil.
Finally they both return to the workshop. While the second car now starts to realize he will have to take the time to be properly fixed, the first car wait impatiently, already backed out of the workshop half way.
It's tired of being held back. Tired of the polluted environment. It wants to be free of it's travelling companion.
The second car now realizes it should have had it's rings fixed as soon as he realized they where worn. He is now filled with regret, for the first car is speeding down the high way, to freedom and it's too late to catch up.

Stay tuned for the moral of the story....
