went to a halloween party and ran into a guy who dropped out of high school after having a mental breakdown. Everybody knew he couldn't control his temper but they were egging him on to drink hard all night. I said hi to him and he said hi back and almost immediately tried to start a fight by saying that he remembered me saying this and that back at school but we calmed him down and he moved on.

As we were heading into town he pulled out a knife and starting stabbing at all the cars on this street, what horrified me more was everyone thought it was hilarious and were egging him on to do more. Then this ambulance comes around the corner and he goes into the middle of the road holds up the knife and starts aggressively shouting come on then, as it went past he was violently stabbing its side as hard as he could.

All the way there he was getting more and more aggressive and was saying how he was going to fuck somebody up, again everybody thought it was hilarious. When we got into town i told everyone i was going home when knife guy said i wasn't going home and pulled out the knife, I said 'fine let me get some cash out then' he said he was coming with me because i wouldn't come back.

im at the cashpoint i get money out when a police car is coming down the road, I say to him hide that knife the police are coming, he holds it infront of him and when they were not 2 metres away I ran infront of the police car making them break hard and he went to chase me remembered he had the knife, threw it at them and ran away.

I got around the corner, hid down this alley way for 15 minutes, then carefully made my way to the taxi rank.

TLDR mentally unstable guy from high school turns up to halloween party, gets badly drunk, pulls out a knife, gets egged on by others and talks about wanting to fuck somebody up
