I want someone who will talk to me honestly about things. You're the only person who ever has. Maybe you don't know this, but when you're disabled almost no one tells you the truth. They feel too awkward because the truth seems too sad, I guess. You were very brave to walk up to the crippled girl and say, essentially, wipe that sunny expression off your face and look at reality. That's what I want you to do next year. Tell me the truth. That's all.
Amy and Matthew didn't know each other, really. They weren't friends. Matthew remembered her, sure, but he remembered a lot of people from elementary school that he wasn't friends with now.
Matthew never planned to tell Amy what he thought of her cheerful facade, but after he does, Amy realizes she needs someone like him in her life.
As they begin to spend more time with each other, Amy learns that Matthew has his own secrets and she decides to try to help him in the same way he's helped her. And when what started out as a friendship turns into something neither of them expected, they realize that they tell each other everything - except the one thing that matters most.
