When the sun sets, it's clear that things have changed. Where the sun has been all day long. It's finally moving now, and it's moving in a meaningful way. The scene shifts as a new sunset appear with every turn. In the same manner that the environment is constantly changing and becoming more distinctive, I believe that life is the same way. Everyone's life is always changing. Sometimes in life, we can tell when things have changed because something or somewhere in our lives has become important to us.
