I haven't experienced anything too traumatic but I have one thing that comes to mind.
A few years ago I found an old lady laying on the ground outside the door to an apartment. It was winter and ice in the ground. I rushed up to her and saw that she was bleeding from her head.
I kneeled down, put her head on my lap, put my jacket over her and applied pressure to her wound. My college called for an ambulance that came 5-10 minutes later and took care of her.
It wasn't long after the news of Omarchy funding hit media that NetworkChuck started shilling for it. I am no longer a subscriber
