Me and Earl and the Dying Girl

Me and Earl and the Dying Girl - Jesse Andrews What was the plot of this book????????
What???????????
It did make me laugh. A lot. I'm sure I sounded kinda insane sometimes.
But overall I just don't understand what the point of this book was????????
I just??????????????????????????
I don't even know what to say. It was hilarious, it was a real quick read, it was seemingly plot-less. I mean, nothing really happened.
Did I miss some pages? Because I feel like this book never went anywhere.
Maybe I'm missing the point. Maybe it was supposed to be realistic in that he had a really boring and uneventful life.
Not that it was badly written. The writing style had me hooked.
And the cover is really nice.
I just feel like I'm missing something here.
