Dear Tobias,
I have lived. I'm going to take Caleb's place. I have a greater chance of surviving the death serum, I know Caleb won't. I know there's a good chance I won't make it out of this, so there are somethings I want you to know before I go, just in case. First, please don't be mad at Caleb if something happens to me, I'm just doing what any sister should. I have lived. Second, I'm just going to come out with it, I'm in love with you. I know fully with all my heart that I love you. I have lived. Third, I haven't been myself since my parents died. I just, I don't know how to explain it, but I've been missing them so much. I have lived. Fourth I have lived. I have a best friend whom I'd do anything for. I fell in love. I've jumped out of trains, gone ziplining, climbed a ferris wheel. I've been with friends shooting muffins off each others heads. People I love have died, I even killed one of them. I've run, I've fought, I've trained, I've worked, I've trusted, I've loved, I've cared, I've killed, I've cried and if this works I'll have saved. I'm going to save my brother. And if this works I'll save my home. And if I don't survive, just know that I have lived. I love you, and I hope you never have to read this and that one day I can tell you myself but if I can't I still have lived. I have lived.
I love you - Tris
