'You seem really down. I don't want to know why, I just want you to know something. You are a lovely person. You're pretty, and like a lot of awesome things, like Star Wars and Black Books (presumably). I don't know you that well, but the moment I meet someone I know whether or not they are a decent human being. You're one of them. There are people who love you. There are reasons to smile. Remember that.'

This means a lot, truly.
You are a very perceptive person, it will get you far.
