This is something that I probably never noticed while growing up in India but I came across something which is distinctly observable during my last few trips around the country. If you are passing through a touristy area, a market place or any busy througfare you will come across a gentleman who will unabashly follow your every movement till you are of no further interest to him.
While passing through the ridge area of shimla (one of the most heavily visited tourist area), I happened to come across a person who kept following me stroll through the area. For some reason I seem to be a curiosity to him (possibly in a manner of how children look at jokers) and on making eye contact there seemed to be no change his nature or stare. After satisfying his curiousity, he settled on other more interesting subjects to monitor. I passed through the area a few times over the next few hours and our starer barely moved a few meters from his original position. This was quite intriguing as I wonder how he actually brings in the paycheck at the end of the month if all he does is stand at one location and watch people move around.
I put this down as maybe people of shimla dont really have anything to do in life and this is the best way to count down the days. This time around I came across a bunch of such people in busy market places and tourist places, so apparently this wasnt a one off incident. So apparently there are people out there who dont really have anything to do in life other than while away their entire life watching and observing the behaviour of others.
