Ha! My brother
was the dog -- when I was eight and he was two, Mom left us in the steep-sloped driveway with the car running for just a moment to go back for something. I was in the back seat, and suddenly my brother yanked on the gearshift and the car started rolling backward. I dove over the seat, and although I couldn't reach the brake pedal, I did have the presence of mind to manage the wheel. I backed neatly across the street, turned as we entered the neighbor's drive, and came to rest backed up against a speed limit sign.
I thought I'd done pretty well, not hitting any cars or people! But of course all I heard from my folks was how I should have pulled the emergency brake.
I didn't even know what an emergency brake was...
