You're my friend—
What a thing friendship is, world without end!
How it gives the heart and soul a stir up!

Robert Browning

Friendship is Love without his wings!

Byron

I do not wish to treat friendships daintily, but with roughest courage. When they are real, they are not glass threads or frostwork, but the solidest thing we know.

Emerson

Nothing makes the earth seem so spacious as to have friends at a distance; they make the latitudes and longitudes.

Henry D. Thoreau
