Keep your friends close, but your enemies closer
-Al Pacino
He spoke the line, but the film was written
by Mario Puzo and Francis Ford Coppola.
(Still, that’s better than attributing it to Sun Tzu or Machiavelli…)
The only way three people can keep a secret is if two of them are dead. -Benjamin Franklin
My first instinct was “No way,” but it turns out old Ben really
did write “Three may keep a secret, if two of them are dead”
in Poor Richard’s Almanack.
