There are times when I worry about myself. Take yesterday afternoon, for example. I walked the dog and, on returning to the car, opened the boot and let her in. (It is an estate car.) Then I walked round the side and opened the door. As I sat down I wondered what had happened. It didn't feel the same as my seat. I shut the door and then noticed something was missing: the steering wheel.
I'd only opened the back door and got in.
