In high School I got jumped by 4 thuggish lookin dudes I had never seen before. While they ran up on me and my friend I was in shock thinking they were running past us instead of at us. Anyway I stood there and then a skinny tall dude dropped an elbow on my head and made my vision blurry as fuck, then my friend tried to fight so I watched him fight one for a second, then all I remember was I got socked in the eye bone and got a black eye. Its a different question with a friend there but If I were by myself Id be out no question about it, but that Fight or flight thing in your brain doesnt ask for reasons, you do or u dont in any given situation, depends on if u know them, where your at, what your mindstate is, a lot of things
