The books that I read leave a mark on my soul. I feel like every time you read a good book you get more interesting, smart, brave etc. Every book also carries its own lesson that makes you a better person.
Totally agree with this: Honestly, I hated Snape right up until the Deathly Hallows, but the whole time I was trying to see good in Draco. I was so upset at the end, because there just wasn't enough there for him to act on, and it broke my heart.
