"Friendship is almost always the union of a part of one mind with a part of another: people are friends in spots."
~ George Santayana
"Friends need not agree in everything or go always together, or have no comparable other friendships of the same intimacy. On the contrary, in friendship union is more about ideal things: and in that sense it is more ideal and less subject to trouble than marriage is."
~ George Santayana
"Be slow to fall into friendship; but when thou art in, continue firm and constant."
~ Socrates
"If you are successful, you may win false friends and true enemies. Succeed anyway."
~ Mother Teresa
