Gentle Reader, it's always important to have gasoline inside the gas tank. It's difficult to drive the car without gasoline. The Gentle Reader could try to drive a car without gasoline, but the Gentle Reader won't make it very far. So it's very important for the Gentle Reader to make life much easier. When the Gentle Reader realizes that the gas tank is about to become empty, always take time to visit the gas station to refill the gas tank before the gasoline runs out. Trust me that it would save the effort of walking back to the gas station to purchase a plastic gas can, fill it up with gasoline and then get the roadtrip continued. Just another helpful hint to make life much easier.
And as I'm lost in thought about gasoline and gas cans, here are some photos of Natalie Portman.
