Inspired by another great thread. Can I ask what things you did as a kid that were pretty outrageous?

[Winter7]

Not sure if I am allowed to reference other thread but op's son was involved in a pretty brave but funny prank.

Got me thinking. When I was about 14, a group us us planned to camp out in our school overnight. Up in the rafters of a very old building. It was more of a ghost watch adventure than anything more troublesome. We packed a picnic, sleeping bags and torches. No phones or such at the time. A couple of our parents wouldn't let some of our group 'stay over' at our make believe sleepover and our plan never went ahead. I still shudder when I imagine the trouble we could have been in. Never once did we consider alarms going off!
What youthful mischief did other mumsnetters get up to that as adults you now think was a terrible idea?

I went to boarding school and one of the lads opened a weed shop from the kitchen window during the night. Kids would walk up to the house, quietly knock on the window and then be served like a corner shop.

Also used to be an Internet chat room fiend. The amount of times me and mates would lie and say we were 25 and would chat up loads of older blokes. We were only about 11. Parents had no idea what we were up to

Train surfing. Only on the local branch line so no chance of meeting another train coming the other way but still really fun stupidly dangerous. Also swimming in the local gravel pits and river.

My father was a clergyman in London. We regularly had tramps staying in the vicarge, downstairs from where we were.
We had charity form Daughters of the Poor Clergy', doubt it exists now.
But I regularly took cash from my father's coat pocket to use either to buy for other people or to get for myself ( crisps, chocolate) as I didn't want to seem 'poor'. My lunch was 4 ryvitas with cottage cheese in between that I had to make myself over the stare of my mother's eye the night before and they were truly soggy by lunchtime the next day. I threw it all away.

I remember feeling sick with sickness at myself for having done this and was quite down as a teen at school because I did this.
I can now understand it but it still has the power to take me to another wretched place.

I ran away with my best friend to London when our mock exams were taking place. We'd both had arguments with our parents over something I can't remember and were pretty fucked off, so agreed to run away. Originally we were going to aim for the Greenham Common Peace Camp, but decided London was probably the better option to disappear into. We hitch hiked there with the help of lorry drivers (thankfully none were pervy) and went to stay with her grandfather's 'lady friend' in Woolwich. After getting lost numerous times, despite my friend claiming she knew London 'like the back of my hand', we finally arrived at the Lady Friend's flat whereby she immediately made us feel incredibly welcome. She was a lovely old Scottish lady and after making us dinner, she gave us shortbread and whiskey! Then she grassed us up to my friend's grandfather and he came around the following day to give us both a talking to. In the meanwhile our parents had been up all night planning the consequences we were going to face when they found us. My friend's dad drove down to collect us and we reluctantly went back with him. As we left Woolwich and the kind Scottish Lady Friend, my friend asked her dad if we could be driven through London ' to see the sights' ...which he quite rightly refused! On my return home, my mother had stripped my bedroom bare. My band posters...everything personal was taken down and put away...even my crimpers. I was grounded for a month.

I grew up in 2 locations in London, very close to major railway stations. I would regularly take a short cut over the sidings, live lines and all.
