Who seeks a faultless friend rests friendless

Friendship is love with understanding

A good friend is better than a near relation.

To attract good fortune, spend a new penny on an old friend, share an old pleasure with a new friend and lift up the heart of a true friend by writing his name on the wings of a dragon.

True friendship is not measured in days or decades.

Meddle not in the affairs of the dragon; for you are crunchy and taste good with ketchup.
