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.
~ Oliver Wendell Holmes.
"A sympathetic friend can be quite as dear as a brother."
~ Homer (9th century B.C.).
"Your friend is the man who knows all about you, and still likes you."
~ Elbert Hubbard.
"Who finds a faithful friend, finds a treasure."
~ Jewish saying.
"We cannot tell the precise moment when friendship is formed. As in filling a vessel drop by drop, there is at last a drop which makes it run over; so in a series of kindnesses there is at last one which makes the heart run over."
~ Samuel Johnson.
