How are the style and tone of the narrator's voice different from
those of the characters?

To find a good man is to start off seeing wut you have in common with
him.after you who his friends are?The main thing is to see if he has a
real anger problem.See if he has a steady job or career.finally you do
make sure he aint no player.Thats all you need to find out to have a
nice man.Later

Narrator's voice is deeper, more of a monotone and often faintly
British to American ears. Listen to the BBC announcers and you get a
nice narrator quality.
