Masterful write. I find it hard to believe you're 22, and possibly have written this when you were 20. There's a mature feel to it, and the conscious ride reading this piece gives an attitude rare in this site. Good job!
There's so much that can be understood from this poem. To make it short, I just love each of the examples you gave, i don't think you used them randomly rather i feel they were meant to be there.
The ending was perfect.
This poem can show that no one is happy the way they are. That everyone may feel left out, like they don't fit in, just like the rhyme, the rhyme for orange seems to not get along with other rhymes. The swaying from left to right out of the branch of the tree, not knowing where destiny will make it fall, in what grounds? Or if someone will catch it... And I think I am doing it again, it can't be help I am rambling, but I did enjoy this one. Sorry for my misplace punctuation.
