to share a joke,
to perform mutual acts of kindness,
to read together well-written books,
to share in the trifling and the serious matters,
to disagree though without animosity --
just as a person debates with himself --
and in the rarity of disgreement to find the salt of normal harmony,
to teach each other something or to learn from one another,
to long with impatience for those absent,
to welcome them with gladness upon their arrival.
These and other signs come from the heart
of those who love and are loved
and are expressed through the mouth,
through the tongue,
through the eyes,
and a thousand gestures of delight,
acting as fuel to set our minds on fire
and out of many to forge unity.
This is what we love in friends."
~ Augustine, 397 A.D.
