I will be responding to the same question as last week:
What was the author's purpose(s) in writing this book, and how can you tell? How well was this purpose achieved?

I stand by what I said earlier, but now I believe I can find out even more expanding off of what a previously wrote. Dave Pelzer, author, writes,
“The story has two objectives: the first is to inform the reader how a loving, caring parent can change to a cold, abusive monster venting frustrations on a helpless child; the second is the eventual survival and triumph of the human spirit over seemingly insurmountable odds.”
The second objective is easy to see. David is always struggling to stay motivated. He is blinded by his mother of a world outside the “madhouse” they live in. Little things keep him going; even the lies that he knew weren’t true. No matter what it took, David stayed as optimistic as someone could be in his situation. Of course, David is not like every child, some don’t make it, fortunately, David was special, he kept himself busy by staying strong and not letting his mother get anything out of hurting him.
Of course there was another objective for the book, this one harder to see. Pelzer explains that he wrote the book to show how a caring parent can turn into a monster. Based on what I have read, I believe that this happened because there was so much stress on David’s mom to be perfect that she cracked and blamed all of her imperfections on David. Pelzer explains that a lot of the time parents take their anger out on their kids. The weird thing about this situation was that the mother, at one point was a loving, caring parent. Another possibility is that there could have been problems in the marriage between David’s mother and father. Because she is completely unable to harm a grown man, she hurts David instead. This may also be a reason that David’s father was completely unable to help; he felt like his son’s hardships might have been his fault.
