At some point in our childhood, all of us would have found ourselves with a large lump of modelling clay in our hands. While some of us were quick to shape this lump into mountains or flowers, many of us were satisfied with simply being able to roll it up and flatten it out repeatedly. However, after a while of playing with the clay, the same feature that made it so interesting would suddenly become a hindrance. This feature is its malleability. No matter how much effort we may put into creating a beautiful model, we would always know that it would all have become one great lump again when it was time to pack up. What was the point, then, of spending so much time and energy on something that would never be permanent?
