“Ever lived with a cat? No, I see you haven’t. How can you have the gall not to like something you don’t know anything about? Wait till you’ve lived with a cat, then tell me what you think. Until then...well, who told you you were entitled to an opinion?”
“Huh? Why, everybody is entitled to his own opinion!”
