I once drove a friend's car to the grocery store to pick up some cranberry juice for her (she had a UTI). When I went to get in the car, I realized that I hadn't paid attention to the colour or even the make of the car. I stood there staring at the cars in the parking lot and wondering which one it was. I realized the key said what brand it was. Then, I remembered she had out of state plates, so I just looked for a Ford with a license plate from the right state. I felt like such a dolt for not paying attention to what kind of car I had borrowed or where I had parked it.
