At the age of about ten or so, a friend and I suddenly thought it would be a good idea to start throwing things at cars; we started off with handfulls of berries, but eventually he dared me to throw a stone - I stupidly did as I was told and broke the windscreen of a (slowly)passing vehicle; the driver leapt out and ran after us - (apparently) I ran home and changed my clothes, but it was no good; he had seen where I went. I got in terrible trouble over that one.
Later on, at secondary school, I was equally easily led; some boys decided they would go into a classroom at lunchtime and steal a big wad of exercise books; I tagged along. They took the books, but didn’t really know what to do with them - I’m not quite sure how, but they ended up being hidden in my bedroom; then one of them went home and told his mother all about it. Because all the evidence was found in my possession, I took the brunt of the punishment and was not allowed to go on the school holiday trip (an educational mediterranean cruise).
For some stupid reason, I also tagged along when one of the same boys decided to steal half a kilo of metallic calcium pellts from the chemistry lab - again, we got caught when he put a huge heap of them into a container of water in one of the lunch rooms.
There have been others, but all with the same kind of pattern; looking back, I really must have been the most impressionable and gullible dullard imaginable.
