"Mediocre people have an answer for everything and are astonished at nothing. They always want to have the air of knowing better than you what you are going to tell them; when, in their turn, they begin to speak, they repeat to you with the greatest confidence, as if dealing with their own property, the things that they have heard you say yourself at some other place. A capable and superior look is the natural accompaniment of this type of character." -
