(Man—Peter    Woman—Ann)
M: Hi, Ann, let’s start planning the office Christmas party.
W: Good idea!
M: First, Ann, do you know how many people will come?
W: Well, last year two people didn’t come and everyone brought a friend. That means there were 46 people.
M: Okay, but this year we’ve hired two more secretaries. One of them is married and one is not. I guess we should plan on everyone coming and bringing one other person.
W: Then that would mean 54 people.
M: That’s a large group. Do you think that we can fit that many people into our conference room?
W: I think so and if we want some extra room we can open the small rooms on the side of the conference room.
M: Then what should we do about food?
W: If you remember, last year the office kitchen agreed to give us snacks and drinks. It worked just fine, I thought. No one wants to eat too much because most people will go out to eat after the party.
M: Yes, I’ll contact them again. I remember they had those hot snacks that were delicious.
W: How about time?
M: We’ll stop work at 3 in the afternoon on December 24 so we’ll start the party at about 1 PM and everyone can leave when they wish. We’ll hand out the Christmas bonuses right at the beginning.
W: It sounds like a good plan. I can hardly wait until the day before Christmas.
