Veronica Roth said this quote

I have a scar-a faint gouge in my knee from when I fell down on the sidewalk as a child. It's always seemed stupid to me that none of the pain I've experienced has left a visible mark; sometimes, without a way to prove it to myself. I began to doubt that I had lied through it at all, with the memories becoming hazy over time. I want to have some kind of reminder that while wounds heal, they don't disappear forever- I carry them everywhere, always, and that is the way of things, the way of scars.That is what this tattoo will be, for me: a scar. And it seems fitting that it should document the worst memory of pain I have.
