Oliver Wendell Holmes Sr.

“Don't flatter yourself that friendship authorizes you to say disagreeable things to your intimates. The nearer you come into relation with a person, the more necessary do tact and courtesy become. Except in cases of necessity, which are rare, leave your friend to learn unpleasant things from his enemies; they are ready enough to tell them.”
― Oliver Wendell Holmes Sr.

“What refuge is there for the victim who is possessed with the feeling that there are a thousand new books he ought to read, while life is only long enough for him to read a hundred?”
― Oliver Wendell Holmes Sr.
