He who has a thousand friends has not a friend to spare, And he who has one enemy will meet him everywhere.
The mind of a wise man is the safest custody of secrets; cheerfulness is the key to friendship; patience and forbearance will conceal many defects.
Your friends are three and your enemies arc (also) three. Your friends are: your friend, your friend's friend and your enemy's enemy. And your enemies are: your enemy, your friend's enemy and your enemy's friend.
