Sense

When you stop telling your friends everything about your life, your enemies will be helpless due to lack of information.
There will be no opportunity to spread gossip. No one will be able to criticize your decisions.
Not everyone you consider or call a friend is a true friend.
Some people pretend to be your friend just to pass on news to their enemies.
Be careful who you consider your friend, because one of the most dangerous enemies in the world is the person who gains your trust by pretending to be a friend.
Secrecy is your strength; what people don't know, they can't destroy.
