I've seen some traumatic things but the only thing worthy of a thread like this (or really that I can't forget even though my memory is a sieve) is from when I was around 15/16. I had an abusive boyfriend who was quite nasty, not a good soul. We were at a skatepark in Kensal Rise. He was doing his thing all day and I was just watching, some maybe 14 year old chubby lad was there and I was speaking to him most of the time. He was very nice. I asked him if he knew anybody with weed locally and we ended up going on about an hour long walk through London to get some. We got back to the skatepark and I was chatting to him the whole time. Towards the end of the day it was going to get dark but still daylight. A group of boys probably 11-14, maybe 6 of them? Come to the skatepark. None of them are riding. I'm not paying much attention but I noticed they were just sitting opposite us. So the young chubby lad said he was going to go, and started walking off. There was probably a 5 min walk to the main high street and the skatepark itself was under a bridge so it was quite isolated. Anyway as he walks off, they all jump up quickly behind him. Less than 10 seconds later I hear a commotion and I jump up to see where theyve gone. They're absolutely beating and kicking the shit out of this boy, stamping on his face, 6 of them, who easily could've just taken his stuff and he would've obliged. I was in shock and they carried on as I was standing 2 meters away, my ex motioning to get the fuck back to him. I went over and begged him to say something, we both went over and I think all he said was "that's enough" with a sort of agreeing face on him. They went off with his oyster card, and that was literally it. I helped the lad up and his face had been entirely rearranged. His nose was on the other side of his face and eyes so swollen he could barely see, and his forehead was a few inches protruding, covered in blood. Ears swollen. Horror show. I said we need to call an ambulance, are you okay, we walked towards the high street and my ex dragged me off and said we need to go NOW. I was young and my biggest regret to this day is leaving, I didn't call an ambulance, I didn't do anything, because I was terrified of both the boys coming back and of my ex. What truly disgusted me is we rode off on his demands leaving the boy by the main road, and we rode in a different direction to how we got there down some dirty estate. We happened to see the boys ahead. I was scared, but my ex decided to pull up and have a chat with them. What was that all about, he said, while kind of laughing like he was on their "side"...they all had a laugh as I stood back in disbelief and then we took off back home. I have stood up to people ever since in all sorts of situations almost getting stabbed once by a crckhead on a train trying to mug a young boy. But that one occasion I did nothing because of the control my ex had over me and I didn't know how to react, also scared they would turn on us. I still think about him to this day, the injuries were serious. He was walking straight after but he was truly battered to a pulp, for nothing. I will always regret doing nothing, not even calling an ambulance. Before I get judged which I do accept, I was very young in a relationship that traumatised me even to this day I bear the scars from it. But that will always stick with me. Nice young boy going to the skatepark by himself no fear, leaving with terror and probably not going out alone again for a long long time. Never saw anything on the news about it. I think about him often.
