F: Hi, Albert. You know, John won first place during the chess competition and we've been asked to organize a party for him. ,M: Yeah, sure. It's about time we started to prepare it. ,F: Exactly. And when is the best time to hold it? ,M: Well, John will leave for Boston next Tuesday. ,F: So what about 2 days before he leaves on May thirteenth? That's a Sunday. ,M: Sounds nice. ,F: What about the place, at school or at a restaurant? ,M: I think it'll be expensive if we hold it at a restaurant. John said his grandparents welcome us to their big house. ,F: Great. And then, we ought to be thinking about invitations. Who must we invite? ,M: Well, John's chess coach. ,F: And John's parents? ,M: Yes. Besides, we'll invite at least 5 teachers and 20 students.
