“Never break a promise to an animal. They're like babies—they won't understand.”

“That's the point. Every kind of animal thinks its own kind of animal is wonderful. So people getting married think they're wonderful, and that they're going to have a baby-- that's wonderful, when actually they're as ugly as rhinoceroses. Just because we think we're so wonderful doesn't mean we really are. We could be really terrible animals and just never admit it because it would hurt so much.”

“Sometimes people don't understand the promises they're making when they make them.”

“I hope that when machines finally take over, they won't build men that break down, as soon as they're paid for.”

“Always' was a promise! How can you just break the promise?" "Sometimes people don't always understand the promises they're making when they make them," I said.Isaac shot me a look. "Right, of course. But you keep the promise anyway. That's what love is. Love is keeping the promise anyway. Don't you believe in true love?"I didn't answer. I didn't have an answer.But I thought that if true love did exist, that was a pretty good definition of it.”

“Never believe a promise from a man or woman who has no discipline. They have broken a thousand promises to themselves, and they break their promise for you.”
