“I can be a good friend, or a bad enemy.”

“A man with no enemies is no good as a friend.”

“I choose my friends for their good looks, my acquaintances for their good characters, and my enemies for their good intellects.”

“The enemies of your enemies are not always your friends, but they can still be useful.”

“Friend, my enemy, I call you out. You, you, you there with a bad thorn in your side. You there, my friend, with a winning air. Who pawned the lie on me when he looked brassly at my shyest secret. With my whole heart under your hammer. That though I loved him for his faults as much as for his good. My friend were an enemy upon stilts with his head in a cunning cloud. -Dylan Thomas”

“I have no trouble with my enemies. I can take care of my enemies in a fight. But my friends, my goddamned friends, they're the ones who keep me walking the floor at nights! ”
