This book really went into showing you how different people live life and how they experience their day-to-day lives. You see life through the eyes of almost every possible life there is to live. It showed me that people grow up and live in different circumstances and that these circumstances and events shape them all in individual ways. 
It shows you that judging books by their covers isn't the way to go because you never know what people go through. 
It was a real eye opener to me and yet still very interesting to read
