irst to break off from thy friend. Sorrow will
eat thy heart if thou lackest the friend to open thy heart to.

Anything is better than to be false; he is no friend who
only speaks to please.

Which means, of course, that a true friend is not afraid to find fault
with his friend's course; indeed, that is his solemn duty. But these
teachings about friendship are accompanied with many cautions; for one
must be very careful in the making friends. The ancient Greeks had a
terrible proverb: "Treat your friend as if he should become some day your
enemy; and treat your enemy as if he might some day become your friend."
This proverb seems to me to indicate a certain amount of doubt in human
nature. We do not find this doubt in the Norse teaching, but on the
contrary, some very excellent advice. The first thing to remember is that
friendship is sacred: "He that opens his heart to another mixes blood with
him." Therefore one should be very careful either about forming or about
breaking a friendship.

A man should be a friend to his friend's friend. But no man should
be a friend of his friend's foe, nor of his foe's friend.

A man should be a friend with his friend, and pay back gift with
gift; give back laughter for laughter (to his enemies), and lesing
for lies.

Give and give back makes the longest friend. Give not overmuch at
one time. Gift always looks for return.

The poet also tells us how trifling gifts are quite sufficient to make
friends and to keep them, if wisely given. A costly gift may seem like a
bribe; a little gift is only the sign of kindly feeling. And as a mere
matter of justice, a costly gift may be unkind, for it puts the friend
under an obligation which he may not be rich enough to repay. Repeatedly
we are told also that too much should not be expected of friendship. The
value of a friend is his affection, his sympathy; but favours that cost
must always be returned.

I never met a man so open-hearted and free with his food, but that
boon was boon to him--nor so generous as not to look for return if
he had a chance.

Emerson says almost precisely the same thing in his essay on
friendship--showing how little human wisdom has changed in all the
centuries. Here is another good bit of advice concerning visits:

It is far away to an ill friend, even though he live on one's
road; but to a good friend there is a short cut, even though he
live
