I was in a sport team for a while and they hadn't been treating me well for a while. One day, I slipped and fell during training. Instead of somebody helping me up, the majority of the team laughed at me. Something in my mind snapped that day and it nearly led to my first ever physical altercation. However, my punch just turned into a feint with the thought "fuck this, I'm out".
That was the day I learned not to let things boil until they explode. Put me into any salad and I'm not the calmest cucumber, but I have never let things get that close again and always speak up or just straight up leave before getting too heated. Life's just too short to stay in a bad situation you can get out of.
