" Jaime reached for the flagon to refill his cup. “So many vows . . . they make you swear and swear. Defend the king. Obey the king. Keep his secrets. Do his bidding. Your life for his. But obey your father. Love your sister. Protect the innocent. Defend the weak. Respect the gods. Obey the laws. It’s too much. No matter what you do, you’re forsaking one vow or the other. "

― George R.R. Martin , A Game of Thrones / A Clash of Kings (A Song of Ice and Fire, #1-2)
