I agree with you on this. I posted something similar a few posts up. Some people are hard wired to fight, not run. I'm one of them. Actually I slugged my Dh really hard one time by mistake. I was walking out of a store downtown in the dark by myself, he happened to see me and 'stalked' up behind me and grabbed my purse and pulled. I came around with a mean right hook and caught him very unaware knocking the air right out of him. He doesn't try to spook me anymore .. Even the kids know you don't creep up on mom cause she doesn't jump, scream or run .. she turns with her fists clenched, legs crouched in a fighting posture and ready. I've always been like this, I wailed my Dad once when I was just a kid for jumping out at me. I even went after a person in a haunted display once when I was about 9 yo because he decided to take scaring me and my brother too far and kept persuing instead of backing off. Good thing for both of us he was fast on the dodge, since I had cowgirl boots on and was going for the kill. Put some people in a fight response and your going to get more than you bargained for.As far as the 'jerk', ...Flight or Fight - it's a natural response.
