“...though I cannot promise to take you home," said North Wind, as she sank nearer and nearer to the tops of the houses, "I can promise you it will be all right in the end. You will get home somehow.”

“I can't promise not to make you mad. I can't promise that I won't hurt you. All I can promise is that I want you in my life, and I'll do anything to keep you there.”
