the five people you meet in heaven

Ok so for my english class, our final project consisted of us each reading any book we wanted to (under few circumstances) and then expressing how we felt about the book through various ways. I chose a blog as one of my ways to express how I felt about my book. I am reading The Five People you Meet in Heaven by Mitch Albom and let me begin by saying I have fell in love with this book. Many people saw me reading it and told me they had read the book as well and how they enjoyed it too. However a very common question was "So, who are the five people you meet in heaven?"
