You drove and pulled up to the gas station to fill your gas tank. You exited your vehicle, opened your gas tank cover, grabbed and put the dispenser nozzle in. You also had to pay at some point.
How can you forget that the hose is still connected to your car when you drive off?
Imagine you get back after a long, hectic, infuriating day. You hear your car beep for fuel so you pull into a gas station.
You get out and you go through the motions of filling up your car. It is such a usual procedure you don’t have to think any more. Which is good because you’re using that time to think of choice words to describe your asshole boss.
You go into the station, pay and come back, still very much on autopilot while you think about your boss.
Except there’s one motion you didn’t go through. And now it haunts your gas tank forever. Until you take it off.
