John Green, The Fault in Our Stars

"Love is keeping the promise anyway."

"I'm in love with you, and I'm not in the business of denying myself the simple pleasure of saying true things."

"Sometimes people don’t understandthe 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’swhat love is. Love is keeping the promise anyway. Don’t you believe in true love?"

"Augustus," I said. "Really. You don't have to do this."Sure I do," he said. "I found my Wish."God, you're the best," I told him."I bet you say that to all the boys who finance your international travel," he answered."

"I’m in love with you, and I know that love is just a shout into the void, and that oblivion is inevitable, and that we’re all doomed and that there will come a day when all our labor has been returned to dust, and I know the sun will swallow the only earth we’ll ever have, and I am in love with you."

"I was blind and heart broken and didn't want to do anything and Gus burst into my room and shouted, "I have wonderful news!" And I was like, "I don't really want to hear wonderful news right now," and Gus said, "This is wonderful news you want to hear," and I asked him, "Fine, what is it" and he said, "You are going to live a good and long life filled with great and terrible moments that you cannot even imagine yet!"

"I'll fight it. I'll fight it for you. Don't you worry about me, Hazel Grace. I'm okay. I'll find a way to hang around and annoy you for a long time."

"As he read, I fell in love the way you fall asleep: slowly, and then all at once."

"I'm in love with you," he said quietly."Augustus," I said."I am," he said. He was staring at me, and I could see the corners of his eyes crinkling. "I'm in love with you, and I'm not in the business of denying myself the simple pleasure of saying true things. I'm in love with you, and I know that love is just a shout into the void, and that oblivion is inevitable, and that we're all doomed and that there will come a day when all our labor has been returned to dust, and I know the sun will swallow the only earth we'll ever have, and I am in love with you."

"Some people don't understand the promises they're making when they make them," I said."Right, of course. But you keep the promise anyway. That's what love is. Love is keeping the promise anyway."
