I found it difficult to begin this post, I really did.
I won't be able to write much about Augustus because, well, he sort of died. And I intentionally put that "sort of" there. I think one of the hardest things one can experience in life is talking about someone you love in past tense. Past tense does not necessarily mean death, of course, people get in and out of our lives all the time. But them leaving doesn't mean we forget them. In fact, I think that losing them just makes the memory stronger. Remember that Augustus feared oblivion? He eventually got to the conclusion that "the real heroes anyway aren't the people doing things; the real heroes are the people NOTICING things, paying attention." (I completely agree with him) Augustus will live in the memory of Hazel Grace, of his parents, his family, his friends... and perhaps they will tell their children about this friend they had named Augustus Waters, who liked metaphors, and hated basketball, and who spent his Cancer Wish on taking his girlfriend to Amsterdam so that she could meet her favorite author.
Augustus Waters left his mark. He left his scar. And like that, he defeated oblivion.
