Catcher in the Rye

Chapter 22 is the second time catcher in the rye is mentioned. The first is when the little boy is singing the song and it is then mentioned when Holden says all he wants to do it be this 'Catcher in the Rye'.   I really don't understand Holden when he says this is what he wants to be. Why does this even enter his mind, because what kind of job would he be catching children in the rye. Why couldn't Holden choose some 'normal' sort of profession, and somehow make it work? After talking about it in class I think this is also showing Holden is scared to grow up. He wants to stay young and immature and he wants everything to stay the same. He doesn't like change and sometimes I think he is scared of it. "Thousands of little kids, and nobody's around-nobody big, I mean-except me... What I have to do, I have to catch everybody is they start to go over the cliff". I took 'the cliff' as adulthood. He also used the frozen pond to symbolize adulthood earlier.  I think this title fits because this whole book is about Holden not falling off the cliff. Maybe he thought of this job because he wished there was somebody to catch him when he falls. To me, this book can be about his struggle with how to cope when he eventually does fall of the cliff. His ideas of running away are just another possibility Holden thinks he can escape it; never talk to anyone and live life on his own terms.  But, honestly, I don't think Holden would have been able to do it. He would have been too lonely and missed people too much, no matter he thinks they are all phony.
