Being adopted felt like reading a book that had the first chapter ripped out. You might be enjoying the plot and the characters, but you'd probably also like to read that first line, too. However, when you took the book back to the store to say that the first chapter was missing, they told you they couldn't sell you a replacement copy that was intact. What if you read that first chapter and realized you hated the book, and posted a nasty review on Amazon? What if you hurt the author's feelings? Better just to stick with your partial copy and enjoy the rest of the story.
