Tell me about your most dangerous encounter?

I have only faced serious possible physical harm from another person one time in my life. It was when I was an independent trucker and at a rest area. There was another truck parked behing me and its driver was doing something near the back of his rig. Suddenly, he stopped whatever he was doing and looked at me. That is, glared at me. Then he started running in my direction as fast as he could go. As I was standing right near the door to my truck, my first instinct was to jump into the truck and lock the door. Then I thought to myself, that as I once was a soldier and was trained to not be a coward, I was not going to run, if he wanted a fight. Hence, I took the folding lock back knife I carried out of its sheath, opened it, and turned to face the man. When he saw this, he literally started back peddling in mid stride. He could not stop running fast enough. He went to his truck climbed in and drove off as fast as he could. To this day I have no idea what this man was thinking. There was no way he could have gotten to me, if I wanted to run, before I could have gotten into my truck, so robbery or mayhem just does not make sense to me. Maybe he thought I was someone else? I'll never know.

Mine is during that time when i come home from work riding a jeep with my cellphone inside the pocket of my back when i suddenly noticed that the person sitting next to me is trying to get it out from my bag. Yet i haven't react because i'm afraid if he will hurt me...
