Personally I follow the "if they see it, they are hearing it" and don't allow those who may need some dicipline to know that they are approaching a diciplenarian.
So our OP gets a thumbs down on the show and tell.
However the level of agressiveness in our local panhandlers "shakedown artists" is seemingly growing at a quick pace, and I think must be matched.
We all and sundry realize that those who would aggress against us, pick those of us who give the impression of easy pickins. A strait spine ,determined step, and level gaze, has probably averted(or re-directed) more anti-social behavior, than any Expressed show of beligerance.
I would like to let our young friend(theOP) know that while admiring his grit,
and alertness, it's the snake that doesn't rattle, that does the biteing.
OP; ya done good, tone her down ,OK?
