I actually have a lot of mixed feelings about this book. It's definitely the most realistic book about a terminal illness that I've ever read, mainly because the author did not romanticize the shit out of cancer. I also related to the narrator a lot, mainly because I'm also a chubby, pasty, self-deprecating, awkward teenager getting ready to leave high school. I also am only funny to older women. I did... like the book, I guess? It didn't make me laugh too much, mainly because my sense of humor is warped (you can blame Tumblr for that) but I did like the characters and the way the plot was executed. I also loved the very realistic feelings and thoughts the characters had. 
 What I didn't especially like about this book was the way it was written. I mean, obviously I can't imagine this book being written from anything other then Greg's first person POV, but I would have liked a little less... breaking the fourth wall? I'm not exactly sure how to phrase it, but Greg constantly saying "This book is pointless" kinda irked me. There were also a lot of parts of the story that seemed kind of mundane, but I suppose that was the point of the story - to make it as realistic as possible. The real world is constantly mundane, and hardly anyone learns any lessons from the death of another person. 
 Maybe I'm just reading too much into it. Anyway, it was a nice quick read. It definitely amused me, so I'd recommend it!
