Dear Mr. Charlie Barnett,
       Thank you for coming!  I had a great time.  I loved plying my guitar for you.  I want to do what you do when I grow up.  Don’t worry, I have an electric metronome.  I drew a guitar for you (on original letter).
                                               Your Friend,

OMG they were all so perfectly wonderful. If it didn’t seem incredibly exhausting, I would want to be a fourth grade teacher.  I wish I could include the picture here.  You will have to use your imagination… he certainly did.
