To give and receive advice - the former with freedom, and yet without bitterness, the latter with patience and without irritation - is peculiarly appropriate to geniune friendship.
No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
These are the things which might conceivably and truly make men forgive their enemies. We can only turn hate to love by understanding what are the things that men have loved; nor is it necessary to ask men to hate their loves in order to love one another. Just as two grocers are most likely to be reconciled when they remember for a moment that they are two fathers, so two nationals are most likely to be reconciled when they remember (if only for a moment) that they are two patriots.
I wish that friendship should have feet, as well as eyes and eloquence. It must plant itself on the ground, before it vaults overthe moon. I wish it to be a little of a citizen, before it is quite a cherub.
A man cannot speak to his son, but as a father; to his wife, but as a husband; to his enemy, but upon terms: whereas a friend may speak, as the case requires, and not as it sorteth with the person.
But remember that the pain of parting from friends will be felt by everybody at times, whatever be their education or state. Know your own happiness. You want nothing but patience; or give it a more fascinating name: call it hope.
