Do all kids grow up?

Holden finally returns home to his little sisters unending love? No. After all Holden has been through he goes home and begins talking to his little sister. As he talks to her she becomes scared for Holden and keeps saying, "Daddy'll kill you". As a growing up child she is beginning to talk like an adult. Already she is beginning to understand what society wants from people like Holden. So, following what she knows about society she lectures Holden about what he should do. Holden however only wants to be with his little sister, not an adult. Holden starts to become annoyed with her uncharacteristic
"adult-likeness". As an article from A science magazine points out humans, unlike other organisms, copy their teachers absolutely. Even if an something is weird or ineffective the child will still follow exactly what the teacher does. This is why Phoebe is unintentionally putting down her brother. What Holden really needs is support and someone to talk to, but since according to society Phoebe should reprimand him, that is what she is trying to do. This shows a fault in our society. I think it would be best if children did not imitate their parents. If they were able to forge their own paths, or in Holden's case, just remain innocent, I think that our society would be better. For example, if a child sees his parents divorce, would it no be better for him to not copy his parents and remain steady with his own wife? Do you think that it is better to have each generation start anew, or to continue to do what our fathers have done?
