Shoes Growing On Trees

It's easy to see shoes hanging from trees and light posts all over the city. But, this tree on 3rd Street, between 2nd and 3rd Avenue always cracks me up. Granted, it doesn't compare to some others out there. But, it's got a little something going there. So, it leads me to the inevitable question: why? Why would someone feel the need to throw away a perfectly good pair of sneakers? I understand the mass-madness caused when someone sees a place that others have left their mark inspiring them to do that same thing; thus negating that unique impulse. But, what caused that first impulse. Is it the mark of a teenage boy celebrating his loss of virginity? Was it a cruel joke played on a small teen by other bigger teens? Was it purely a sense of frustration at a pebble being stuck in the lining that made someone pull off their shoes, string them together and thrust them in the air? I honestly don't get it. But, I think that's why I love it. The mysteries of humanity. I hope people always surprise me and make me smile.
