As we grow up in life, we develop a lot of theories of how we think that life works. However, once we get married that begins to change. If we are aware, we begin to see that we don't know as much as we thought. Then, when children come along and begin to grow up, our whole world changes. We realize that we are not the center of the universe, but a small part. We realize that we know very little about how life truly works.
