I'm in the medical field, so there's a lot of shit I've seen at the hospital, but I would say the real craziest thing I ever saw happened when I was in my early 20s. I moved back in with my parents for a time after I had to give up my first apartment. My parents have always had a bit of an unhealthy relationship, they fight like it's their job. My childhood bedroom is always next to the kitchen and front room where they would fight, so I heard a lot of it and sadly just got used to it after so many years, though listening to it constantly as a child formed some core memories in there somewhere.

When I was there in my 20s I would mostly hang out in the separate garage, it helps me to feel like I still kind of had my own space. I worked graves, and would maintain my schedule on my days off, playing video games through the night. One night my dad came out randomly and was in an absolute state, telling me my mom had said "maybe divorce" and a couple other things. We talked at length and I thought I had helped him calm down. He left and I was up for a few more hours. I passed him sleeping in his truck on my way into the house to go to bed, it was weird but I didn't think much of it at the time. Just figured he needed to sleep it off. I had only been asleep a couple hours, when my mom came running, panic screaming into my room at the top of her lungs. She woke me up shaking and yelling that my dad was going to kill himself right now in the garage, that he had the gun and that he said he was going to shoot himself in the face if she tried to stop him. At that moment I saw him passing my room on his way outside. With only a couple hours of sleep ruining my capacity for reasoning my adrenaline went straight from 0 to full blast. I had discovered the nature of their disagreement the night before talking to my dad, so my mouth just ran away before I could think. I sprinted into the hall and caught him by the shoulder , then immediately started shouting all kinds of heinous shit at them about how they were both being "dumb fucks, stupid fucking idiots, immature as fuck" I don't remember the exact words but you get the gist. These are two very religious people who never would have accepted hearing the slightest profanity out of me in regular circumstances, not even the word "god" or the word "hell" (mormons). So yeah, neither of them said anything they both just stood there crying or stunned and listened to me tell them what big fucking morons they were and how immature they were acting, this went on for at least 15 solid minutes, easily the most cathartic thing that has ever happened to me in my entire life, bar none. At the end they were both just kind of stunned, we had it pretty well resolved and they were both calm and I went back to sleep, a testament to just how tired I was in that moment. The three of us have never talked about it again, I think because it all just got resolved right there somehow. Nothing like it has ever happened with them again according to my sister who still lives with them
