 also get questions like, "Did the character in your book grow up, meet a nice person, get married, and have children, also how many?" It's a book. It's fun to imagine the characters are real people and have a life beyond what the book tells, but as the author I'm only responsible for what I wrote. Nothing got cut, it's all self-contained, and it's not for me to locate the sentence or phrase or reference or colloquialism, or pun, or description that you and your mom may have missed, or misunderstood, or just at that moment there was someone at the door, or the microwave went ding. However, I will generously tell you that the female teacher in the book was fired because her mother had insulted the principal when they were both children, growing up in Michigan, and the principal had nursed a grudge, however the fired teacher was offered a job in a first-class school in a very nice suburb, with a substantial increase in salary, rented a lovely little house, loved her new job, met a wonderful person and got married.
