I couldn't get away with much. My dad probably wrote the book on being naughty, he played truant for 6 months and only got found out because the head came to his house one day to see if he was seriously ill and would he ever come beck to school, so he knew all the tricks, so nothing really got past him. My dad probably did enough for my generation anyway.
But I was a general shitbag. crab apples were a favourite. If you found a good stick. One which was the right length and with a bit of flex, you could push a crab apple onto it's end and use the stick to lob the crab apple for miles!
This was the weapon of choice for lobbing crab apples at the windows of the flats until an angry flat dweller would shout at us. We never did the first floor flats incase they chased after us, we wanted a head start.
Plus the usual kids stuff with fires and knives, nothing nasty. A few cuts and minor burns, but nothing malicious. Plus other stupid pranks. Pretty pathetic stuff really.
Then I discovered cycling at about 12. Being naughty was more about going further from home than I was allowed. I used to stash pocket money in my bedroom and save up to buy some drink on my longer rides. It's probably how I got into Audax really. I wanted to ride a long way but always had the time pressure too. The best week was when I set out to do 5 100 mile rides in a week. I didn't manage it. I managed Oxford and back. That was my first 200kride and I did that in about 10 hours. Cambridge and back wasn't quite 100 miles. Northampton and back, I had to give up because I got a bit lost. Being late home would mean my bike getting locked up for the rest of the school holiday, so I didn't risk it. Huntingdon and back was also a bit short of 100 miles, but not by much.. I can't remember the other place now. I still managed over 500 miles in 7 days though.
I was much less of a shitbag though. Maybe there's a lesson there. Give kids something decent to do, that they want to do instead of telling them what they can't do or that it' too dangerous, then maybe they'll do something decent. I think a lot of bad behaviour from kids is because they are bored and frustrated and told that they can't. I think that kids act like shit because they are treated like shit. Reading Clarion's post above, that seems true. That teacher was an adult in charge of kids, but it was Clarion that was the more mature IMO
