I look at it this way. I try to have others control me as little as possible. If I am out walking, minding my own business - why should I have to change my plans and give up my wallet, or whatever it is when I can tell him to back off and continue about what I was doing?
Sorry - but running away at every threat is not the way I want to live my life. I would rather die living the way I choose, than to live knowing I was a sell-out.
