Remember that you are an actor in a play, playing character according to the will of the playwright — if a short play, then it's short; if long, long. If he wishes you to play the beggar, play even that role well, just as you would if it were a cripple, a honcho, or an everyday person. For this is your duty, to perform well the character assigned you. That selection belongs to another.
