The world is like a library, a huge, sprawling archive of every word ever written, and we are the books that line its endless shelves. Everyone has their own personal differences, and no two people can ever be exactly alike. We form our own groups of people we get along with, just like books being sorted into genres. Every person has their own importance in the making up the whole of our world, just as every book is needed to complete a library. And most obviously, every book, every person, has people who care for them, and people who don’t. You can learn something from every book and person you encounter.
