One friend in a lifetime is much; two are many;
three are hardly possible.
~ Henry Adams.
Friendship is the soul's heaven.
~ A. Bronson Alcott.
A friend is, as it were, a second self.
Be gracious to all men, but choose the best to be your friends.
Friendship needs no words--it is solitude delivered from the anguish of loneliness.
~ Dag Hammarskjold.
