I think one or two were written in my teenage diary when I got bored of my own life, but that's another thing that's too embarrassing to look at as a general rule! So, yes, and no. Mind, I think the other things never got as far as paper, to be honest.

Oh, wait, my epic teen fantasies? Oh, yes. Some of them, and some of the later stuff too. Also very embarrassing, but I typed them up on my electric typewriter. They used to get very interesting when I ran out of correcting tape.
