P.S. As you may already know, ThisIsNotTom was created by John Green back in 2009. He's now a best selling author. The movie The Fault In Our Stars was based on a book by him. If you liked TINT and also The Fault in Our Stars, you should check out the book that made me cry when I was supposed to be a super macho teenage boy, Looking for Alaska. You can get it here.
