A: Mr. Lee, I was wondering if you and your wife had plans for next Friday night? B: Yes, I think we might be free. What did you have in mind? A: I've mailed a formal written invitation to your home inviting you to a dinner party at my home. B: That sounds great. Is it casual? A: Actually, we thought it would be fun to have a formal sit-down dinner for the holidays. B: That sounds good. It will give my wife a chance to dress up. A: Yes, we've invited four other couples, so it should be a good mix of people. B: That sounds wonderful. Will there be anyone there that I know? A: Oh yes, everyone we are inviting is from our company. B: Great! I'll look forward to it. We'll make sure and check the mail for our invitation.
