You are an immortal, child-looking girl who has lived since the dawn of the world. How do you pass the time?

Humans are born, they live and then they die. But not for me. So sick of humans having such a short time, I give them the gift of a long live. Since the dawn of time, humans go from children to elderly, they grow, they change and then they die. Some die before their time, some cruelly die when they are young. But everyone will eventually die. <br><br>I am different. I am eternal, for I am the sand of time itself. I am tiny, and live as a child.
