Ok so, while I write I thought I would let you all know what the rest of the letters in Simon's box said, because I thought it would be sort of fun I'm not going to have them all in this one chapter I'm probably going to spread them out and I hope whoever reads this enjoys them.
Jace's Letter
Dear Simon my mundane/vampire acquaintance,
For one thing don't worry about any insults that are too harsh for your feelings, Clary and Isabelle proof read my letter three times each. I'm sure the others have written this, but this box has stuff with sentimental value to remind you of your fantastic times with us. I know you obviously miss me, like any other normal being would, but now I'm going to get serious. Now this may come as a shock to you, but I will miss you as well when I am gone. (I mean who else am I going to argue with in the afterlife?)
Ok, now I need to start being serious, for real this time. I want to let you know that I count you as one of my greatest friends I have ever known, despite everything I have ever said to you. It isn't fair how you have to continue an unfinished life while the rest of us get to grow old and start families. That is why you are a hero to me, because nothing stopped you from trying to keep things normal even when they were fair from it. Continue doing that no matter how hopeless things are, i know you can.
