Dear Bella,
I'm sorry you only get three letters this week. They're making me work now, boring paperwork for some accountancy firm. They know I'm good with numbers which is why they're using me for cheap labor. However, it gives me something to do. As boring as it is, it's better than sitting around doing nothing all day. It gives me extra pen and paper which I will use to continue the book I started here I fully intend to publish our love story one day, although I will leave out this part if you wish.
I love you.
Edward
