Even doctors get it wrong

A letter to the tryanasurus rex, regarding its sudden dissaperance from teh earth and doctors visits x

Dear Tyrannosaurus Rex

You have a rather long and difficult name, i think your parents were some what uanessacry about naming you but anyway im writing in regards to your visit to the doctors all those years back It appears you were suffering from a rather severe case of hyperthermia in which your heart was slowly freezing form the inside. I would of given you this information earlier but you appear to of well vanished off the face of the earth, for a moment i considered trotting down to your musuem and leaving a note on your brother's skeleton but that seemed a little impressonal , so here i am writiting to you nwo, hopeing to reach you feeling better and having a much nicer time. Yours sincerly the doctor.
