I believe a "coming of age" book means that it has a character who matures not only physically, but emotionally and mentally as a person, which basically happens to Chappie in ROB. He grows up and has different stages and slowly he learns more about life, he matures, and loses his innocence. These are some coming of age quotes from the book.
1."She looked at me in this strange fearful way like she didn't recognize me but almost did and I got this sudden new feeling of power and didn't even feel guilty for it. Then she reached into her purse and pulled out a twenty and passed it over... Now I'm a criminal. Now I'm a real Criminal." - this quote from Chappie shows how much he has changed from the old Chappie into a somewhat form of a criminal. he took money from his mother without even feeling bad. He lied, and he never returned home.
2."...I was a way new person with a new name and a new body even and my old identity as Chappie wasn't dead, it was only a secret." -This quote from Chappie shows that he has finally embraced his new self, Bone, after getting his tattoo done. After this, he believes that he is no longer Chappie, but that he is Bone, a completely different person, a criminal.
3."...I didn't look back because i was afraid I'd start crying if I did" - believe this quote from Chappie is significant because it shows that even though he's a "criminal" that he's still a human being with emotions, a human being that can still cry. It shows that we can somewhat relate to him and his feelings and that under Bone, is still Chappie, a Chappie with morals and good decisions.
One coming of age momnet in my life was when i was 5 years old and it was the first day of school ever for me. It was my kindergarten year and my mom dropped me off at school, leaving me for the first time ever in life. I was alone in that classroom even though there were about 20 other children around my age there. I still felt very lonesome, very vulnerable without my mother, so then i cried realizing that this was going to be my first life experience without her.
Another coming of age moment in my life was Only about 2 and a half years ago when my grandmother passed away. Thinking about it now, looking at the body of who onece used to be my grandmother made me realize that none of us stay here on Earth forever. Death is inescapable and we're all going to have to live with that fact. I looked at my grandmother, and although her time on Earth was done with, she was still with me. As cliche as it sounds, she was in my heart and still is to this moment.
