We know our friends by their defects rather than by their merits

However rare true love may be, it is less so than true friendship

A true friend is the greatest of all blessings, and that which we take the least care of all to acquire

Your friend is the man who knows all about you, and still likes you

No man can be happy without a friend, nor be sure of his friend till he is unhappy

It is in the thirties that we want friends. In the forties we know they won't save us any more than love did

Real friendship is shown in times of trouble; prosperity is full of friends

The only way to have a friend is to be one

A friend may well be reckoned the masterpiece of nature

Friendship often ends in love; but love in friendship--never.
