every person of your life occupies a chapter in your book each chapter is different each chapter teaches something different with a different outlook n a different conclusion it's strange but at the end of the day you r not asked whether to save the changes or not? whatever happens becomes a part we want to delete it bt we can't u have a book without a conclusion a person enters ur life recreates a new book gives it a title n a conclusion u don't realize it but it gives u a new story whether u luv it or hate it u have a story a buk that defines ur life a book that reads what u went through u r the author but the writer is someone else who so ever wrote the book might be lost but u are the one to give it an ending just do it :) write a book worth reading
