ِAn offer you can't refuse.

Santino, never let anyone outside the family know what you are thinking. Never let them know what you have under your fingernails. I think your brain is going soft from all that comedy you play with that young girl. Stop it and pay attention to business. Now get out of my sight.

It was a lie but he believed in telling lies to people. Truth telling and medicine just didn't go together except in dire emergencies, if then.

Keep your friends close, but your enemies closer.
