I think that we read book like these because it teach us how persons are and how they act. On these types of books we read that the main characters are best friends. We learn of best friends and relationships. And we also learn how relationships affect decisions and how that can lead you to a complete different situation. Relationships are important in life because are the ones that make you who you are. Persons read books like a hobby, or some of them only because they are asked to. I personally read books because I enjoy reading, it transport you to a complete different world. Maybe the world you are being transport too, you like it more than your own reality.
