Books don't usually make me emotional, but goddamn...
I got so fond of Mark Watney's sense of humor that I now expect all characters to have the same ability to make me laugh. I lost count of the amount of times I laughed out loud in public transport/doctor's offices/lectures, and any other place that is considered socially unacceptable to laugh in, because of how funny this was. The last chapter though is what made it for me, I 𝘢𝘭𝘮𝘰𝘴𝘵 teared up about that ending.
I just finished it and I already want to reread it.
