Okay, I feel quite bad about this and can't work out whether I was BU or not. Yesterday evening I was on the train, it was quite empty but two school boys (maybe 11 or 12) came and sat down, one next to me and one opposite me. Fine, I put my headphones in and was ignoring them. They start playfighting, one of them was waving his arm in my face and they were tussling on the floor by my feet. I got the rage and told them (not shouting), to please calm down and act with courtesy to other passengers, I was fed up of being shoved around by them. So they shut up but kept cough-swearing, like "cough BITCH cough" etc, and laughing etc. I tried to just ignore and chill. One of them got off the same train station, and was basically trying to delay me getting off, kept stopping in front of me, staring at me and saying "what, what?!" at me. He then went to get in his mums car, and I followed and told him that I was gonna tell his mum about his horrible childish behaviour. I didn't obviously, I didn't stoop to that level. But I realise that what I said was childish and I should have handled the situation better, I just felt so ragey. Was IBU to tell him off and how should I have handled it?
