Smile n Nod

I’m getting the distinct impression that it’s very uncool to smile and nod at strangers in my area. I just got back from the gym at my community centre and a quick stop at Bob’s Convenience store and during that time I came across quite a few people and proceeded to do the 'smile and nod' thing to which they semi snarled with annoyance and quickly reverted attention back to their engrossing Blackberry’s. WTF? Is it the smile or the nod? Or is it a combination of both? I guess walking around J&F smiling and nodding at random people is on the same level as farting in the Bay Street TD Tower elevator that is packed to capacity and getting off on the second floor and leaving them to deal with your own special, just had Taco Bell for lunch pew. Is friendly acknowledgement of a fellow human being considered lame or even offensive? Don’t thugs smile? I guess they’ll smile when they find an unlocked, pimped out Honda Civic full of money and horny baby mamas. Horny baby mamas... kinda redundant huh. I must be losing my edge because I don’t remember ever walking around smiling at random people in my shitty, pay for gas before you pump it, urine scented neighbourhood.
