George Eliot said this quote
“ We learn to restrain ourselves as we get older. We keep apart when we have quarrelled, express ourselves in well-bred phrases, and in this way preserve a dignified alienation, showing much firmness on one side, and swallowing much grief on the other. We no longer approximate in our behaviour to the mere impulsiveness of the lower animals, but conduct ourselves in every respect like members of a highly civilised society. ”
