“Seems to me the only difference between your friends and your enemies is how long they stand around chatting before they shoot you.”

“If you are my friend, stand up before me
and scatter the grace that's in your eyes.”

“Count me not your friend but the enemy of your enemies.”

“Your enemies can kill you, but only your friends can hurt you.”

“You know how you’re completely different with your mom than you are with your best friend, than you are with your romantic partner, than you are with your boss? They’re just different facets of me.”

“You and I were long friends: you are now my enemy, and I am yours.”

“If this is how you treat your friends, no wonder you have so many enemies.”

“How do I know I can trust you?'

'You can't,' he said bluntly. 'You've got to take it on faith that the enemy of your enemy is your friend.”

“If you want enemies, excel your friends; but if you want friends, let your friends excel you.”

“If I learned anything Downtown, it's this: the only real difference between an enemy and a friend is the day of the week.”
