A black guy lives near me, I stopped him after seeing him drop litter and told him not to do it.

I said this is where we live and he said "other people do it" and pointed at some rubbish already on the ground. So I said that doesn't mean you should add to it and he went quiet for a second then angrily stated "fuck off".

I was tempted to escalate, but I left it at that.

2 weeks later I heard that he was stabbed to death by his own son.
