Actually I was writing with knowledge: I have been mugged, not just your normal mugging, but an ultraviolent mugging. I was on foot, two guys apprehended me, dragged me to the gutter, beat the living daylights out of me - I could see chunks of skin being kicked off my face but because they had kicked my kidneys in I could not feel anything (adrenaline). I heard more footsteps and thought I might be saved. Alas no, another gang joined in, the first of this group smashing a glass bottle on my head as a way of saying hello. After this went on for a while they dragged me to my feet and demanded money at knife point.
I know what I am talking about. My response to this was to ride a bicycle and never be a pedestrian in that bit of town again. I also moved house, seeing my own blood on the pavement was a bit much!
