Transcript:
Dear Mr. President, I heard that if I wrote you I would get a personal letter back. I will be honest with you. Right now I have no friends at school. but if I had a letter from you everyone would want to be my friend. Please use paper that says the White House so that the kids won't think I wrote it myself to trick them. Also, please write a personal P.S., sort of kidding around and stuff. This better work.
