Who taught you how to ride a bike?
When I was ten or eleven, I tried to learn how to ride a bike. I didn't like it and thought it terrifying. Turning was out of the question; I'd get off the bike, make it point the other way, and get on again.
Then came the fateful moment when I found myself - riding gently down my street, mindind my own business - faced with three obstacles: to the left, a tiny grandmother; in the middle, a group of cyclists slightly older than myself; to the right, a streetlight. Panic took me, and I had to choose very quickly which I wanted to crash into.
So I mowed down the grandmother.
And that, my friends, even though she wasn't seriously hurt, put me off bikes forever.
