I think people are like books. In every person there is a story which varies in length, experience, and essence.
When you first see a book, you see the cover. Although first impressions are crucial, they do not define what is on the inside. As humans we are told not to judge people just as the famous quote explains, "don't judge a book by it's cover." There is so much more to a person or novel that just a "cover". A cover or outside of a person doesn't show the experiences or relationships or failures and triumphs of a story, but as the pages unfold, the stories unfold as well.
Within the book, the pages and chapters may vary in length and quantity, but it is truly what is within the pages that matter. This is where the real magic happens. The core of one's being is not based on the cover or title page, but the story of one's experiences, failures, and what truly makes people who they are. As the story moves along characters come and go, the plot changes, and growth occurs. Change happens. Life happens. That is where the aspect of humanity comes into a novel.
While the plot of novels are always changing, the book itself it too. Some books may be older than others as their pages may be withered or torn. This is not a sign of brokeness, but of wisdom and worth as the book has been through a great deal. Some books are new and some have been read thousands and thousands of time. This doesn't add worth to the novel, just experience.
So when you meet a new person, look past there cover and get to know what truly makes up their life, chapters, and pages. Everyone has a story and everyone should be respected for every page in their story.
