I disagree, if someone hits you on the street and you grin like a fool.. what they gonna be thinking? "I just hit him and hes grinning aout it" GULP. I read a story in Geoff Thompson's book (Dead or Alive), two doormen, trouble is about to kick off, far more of them than the two doorman, they both look at each other and grin big.. the crowd gets nervous and disapates..
