What is the relationship between the child and the adult in Wordsworth’s work?

Wordsworth describes adulthood as essentially the end of childhood and beginning of realization. He reflects his experience with nature from a young age “Though changed,no doubt from what I was first I came along these hills; when like a roe…. “(Lines 66-67) Essentially he is saying as a child one is capable of enjoying it, “climbing” all over it without being aware of the purpose behind it or reflecting on nature. Here he is acknowledging he gained experience throughout life. He views it as a good thing and not a bad thing as he emphasizes, “The still, sad music of humanity…” (lines 91-95) As an adult it is easier to be aware of what nature can provide. Ultimately, after one matures nature can be viewed as a safe place to isolate yourself with anything that me be going on.
