The shadow is always changing. From sunrise to sunset, it follows you with different ways. In the morning, the shadow is very long and it goes towards west. As the sun rises higher into the sky, the shadow becomes shorter and shorter and it is right behind the feet. When the sun goes down slowly, the length of shadow also streches longer . It looks as if there were a stick on the ground. However, it goes east against the way it goes in the morning. If there is no sun, there will be no shadow. Therefore, the shadow will disappear in some days, such as rainy day or cloudy day. And, it will hides itself during the whole night.
