There was a change in my business partner's plan. And Wednesday is the only day she is able to see me. M: That's okay. But we need to find another date. W: I could manage sometime Thursday. How about you? M: Sorry, I got an important meeting all day. What about Friday? W: I'll go to an exhibition in the morning, but I could come to your office after that. M: Great! Look forward to seeing you then. Bye! What was said before this conversation?

M: It's only $410. W: That's really a good price. But my husband hates the cold weather there. So let me talk with him first. M: No problem. What was said before this conversation?
