“Fear is incomplete knowledge.”

“Instinct is a marvelous thing. It can neither be explained nor ignored.”

“Good advice is always certain to be ignored, but that's no reason not to give it.”

“It is a curious thought, but it is only when you see people looking ridiculous that you realize just how much you love them.”
