He keeps finding them. Letters to the Moon full of his woes opened and replied to by an Unknown Responder. He hopes that this Unknown Responder will let his letter be by still writing to the Moon, But a part of him wants to keep this mystery around.

He signs his letter for tonight, he notices that it's addressed not to the Moon, but to his personal mystery. And there are only two words in that letter. "Thank You"
