My favourite poem. The perks of being a wallflower.

This is not an entry in which I am going to write my favourite poem (perhaps only a piece), that is not the goal. I am going to write why I like the poem and why you should read it, is your decision to or not.
As you saw in the picture my poem is part of the book 'The perks of being a wallflower', one of my favourites books. For me, this poem is part of the spine of the book and without this poem the book would not have much sense.
When I read the poem in the book I feel frustrated but at the same time I feel a deep sense of nostalgia and sadness. I'm serious guys, I hope you feel encouraged to read this poem.
I will write a small part of it.

"Once on a yellow piece of paper with green lines
   he wrote a poem
And he called it "Chops"
   because that was the name of his dog
And that's what it was all about
And his teacher gave him an A
  and a gold star
And his mother hung it on the kitchen door
   and read it to his aunts
That was the year father Tracy
   took all the kids to the zoo
And he let them sing on the bus
And his little sister was born
   with tiny toenails and no hair
And his mother and father kissed a lot
And the girl around the corner sent him a

   and he had to ask his father what the X's meant
And his father always tucked him in bed at night
And was always there to do it

Once on a piece of white paper with blue lines
   he wrote a poem
And he called it "Autumn"
   because that was the name of the season
And that's what it was all about
And his teacher gave him an A
   and asked him to write more clearly
And his mother never hung it on the kithcen door
   beause of the new paint
And the kids told him
   that Father Tracy smoked cigars
And left butts on the pews
And sometime they would burn holes
That was the year his sister got glasses
   with thick lenses and black frames
And the girl around the corner laughed
   when he asked her to go see santa claus
[...]"
