Once I went for a walk. I was not a long walk, but not too short either. While I walked, I saw many things. Trees, grass, birds and other things like them. I enjoyed the walk because I saw so many things. I will remember them, they taught me about life. I saw something that caught my eye up ahead. I was interested. I looked forward to getting closer. But when I got there, I saw nothing more than a piece of trash. I could find nothing of value or substance. So I shrugged, continued on my way, course unchanged, and promptly forgot him.
