Drama. The class at school where you had to pretend to be a growing tree (probably loads of other stupid shite but that's all I remember about the first and last lesson I attended). I was scared of having to act like a dumb **** while the other kids got to laugh at me, I was scared my parents would find out I was knocking off school every Thursday afternoon and I was scared of getting caught by the rozzers while I snuck off to the beach. I dreaded it all the time.
Not really in the spirit of this Halloween caper but it's the only thing that came to mind. Apart from my fears of acting, Thursday afternoons, being laughed at, my parents and the police, I was a very brave boy.
