“I’ve had many enemies over the years. If there’s one thing I’ve learned, it’s never engage in a fight you’re sure to lose. On the other hand, never let anyone who has insulted you get away with it. Bide your time and strike back when you’re in a position of strength—even if you no longer need to strike back.”
"The enemies of my friends, are my enemies."
From The Girl With The Dragon Tattoo, by Stieg Larsson
