what thing will you do to make your friendship long?

What is so great as friendship,let us carry with what grandeur of spirit we can Let us be silent, -- so we may hear the whisper of the gods. Let us not interfere. Who set you to cast about what you should say to the select souls, or how to say any thing to such? No matter how ingenious, no matter how graceful and bland. There are innumerable degrees of folly and wisdom, and for you to say aught is to be frivolous. Wait, and thy heart shall speak. Wait until the necessary and everlasting overpowers you, until day and night avail themselves of your lips.
