It is quite fascinating how much our life experiences shape us as human beings, sculpting every minute detail in our human forms. Some of those forms come out shiny and smooth, very pleasant to touch and to come in contact with, with innate abilities to bounce off any light that shines upon them. They might not be too deep, but all you need to know about them lies on the smooth surface, easily visible to the naked eye (unless there are some deeper cracks that might form overtime).
Some come out with jagged sharp edges others might hurt themselves on, and deeply carved crevasses inside which no one is able to see or set a foot. Sometimes it might take a very powerful flashlight to see the wonders hidden in those crevasses, yet sometimes there are no wonders to begin with but cold empty space.
While some may begin as shiny smooth specimens, if touched too roughly, they sometimes may crumble, revealing not so smooth bottom layers. Our shapes may change depending on the amount and quality of experiences that we have, but the main form is usually carved out at the very beginning. Life is a greatest sculptor, but it is our job to monitor the chiseling process and provide the instruments.
