I’m against it. I strongly object. I can’t agree with you. You’re mistaken. It seems to me, that you are not right. That’s not the question. I can’t. No, I can’t tell you. I can’t see much sense in it. Don’t worry.
You are right. Yes. Yes, that’s true. Sounds good. Why not? Certainly. I see. Okay. Oh, surely. With pleasure. That’s right.
