We gave Erika a car when she was 21. Now let me describe the situation with gas. Erika had borrowed my car before, but had never put gas in a car. Of course, we noticed this because the car she borrowed always came back with less gas than when it left. Close to empty sometimes. So, after giving her a car, I had to give her a lesson on filling a car with gas. This is a photo of the first time Erika ever filled a car with gas!
