Reading is like falling in love. Perhaps it is different for everyone, but I feel that sometimes reading means being vulnerable, because you are opening your heart to love people that can never reciprocate the feeling, and because once you do, watching them suffer or die is not all that hard to break you.
And maybe this is why I write; so that I can shelter my characters; so that if it gets too painful, I can always breathe life into the dead with a line or two. So that I will never be broken.
