Hello. Mr. or Mister? A few months ago I received a lesson that said in speech I should write the way people speak. In that specific case we takled about numbers. In speech people don't say numerals, but they say number, so you should write seventy five, not 75. "I am seventy five years old", not "I am 75 years old". I now stumbled upon contraction(s). My character always addresses one person as Mr. Addison. In narrative, I always write Mr. Addison did bla bla bla... But what about speech? Looking at numbers example, I think I should write "Hello, Mister Addison." since no one ever says "Hello, Mr. Addison." But I just wanna make sure. Do I understand correctly?
