Growing up hurts, a lot. When in the process of becoming an adult, we get responsibilities, have to behave properly and act our age. We tend to start ignoring someone very important, the inner child.
Is this why we long back to our childhood so much? Because we miss the person we were back then? We miss the safety, the casualness of just existing. the playfulness of life and a body that could just handle falling down and standing up again. What happens if we become children again? What happens if we try to get back the luxury of unawareness that seems to make the life of a child so pleasant?
