We went during the summer last time, August I think. This time it'll be winter. It's perfect weather there in January. And we'll be able to watch the whales that live there from December to February.
(A) F: All right. So let's go to Mexico in January. (B) F: I am afraid I did not quite catch what you were saying. Please repeat it. (C) F: You're right. So let's go to Japan in February. (D) F: I agree with you. So let's go to Japan in August.

Example Input: F: I wish I could move out of my apartment today. The dishwasher, the fridge and the air conditioning, nothing works well and the landlady just turns a deaf ear to me. ,M: I remember you have signed an agreement with her. Maybe you can find what you can do under the agreement.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Yeah, the unfair agreement is annoying. Can you believe that I don't even have air-conditioning or fridge? (C) F: Well, the landlady has been helpful in dealing with the poor electric equipment, but the problem isn't solved. (D) F: Sounds good. I will see how I can deal with the poor electric equipment, or I'll definitely move out soon.

(C) M: I am afraid I did not quite catch what you were saying. Please repeat it. (D) M: Oh, I'm so sorry that your radio doesn't work. Let me get our manager here, madame.
