Smile is the shortest distance between two persons

A statement like this was put in my front today and it asked for my opinion for as you see the english lesson was the place and to tell my thoughts was the task..at the spot more than one idea came across my mind so now I am here writing it down...

First of all I would like to say that I absolutely disagree with this particular statement for as you see smile can be nor the shortest physical nor mental distance between two individuals for as you see the shortest physical distance is also the smallest space between two objects in this case human beings and smile can definitely not be the shortest/smallest space between two I hope you agree with me on here.. as for the mental closeness and my disagreement in this section too.. for as you see it is quite easy to fake a smile as you might know but if you don't I can surely tell you that by my own personal experience.... but what you can not fake or you can do it only with great art of acting which rare of who has... is the look on you eyes... you can smile with your lips but the truth shall be exposed upon your eyes.... [something disturbed me here and I lost my point]
