Sample dialogue:

S2: Hello. Perhaps I can help. I am Li Feizhou’s secretary. I’m afraid he can only meet you tomorrow afternoon as he had a haircut in the morning. Is that OK?

S1: Oh dear. I was hoping he would be free in the morning as I have another appointment then. It should only take two hours. Maybe we could meet before or after his appointment.

S2: Yes. That might be possible. But he’s busy between 9:00 and 10:30 and then between 11:30 and 1:00 but he might be free for an hour between 10:30 and 11:30.

S1: I don’t think that’s long enough. Could he change his other appointment to another day?

S2: I don’t think so.

S1: Then could he be free at 10:00? We could do the photographs and I would still be on time for my next appointment.

S2: That sounds quite possible. I’ll ask him. What would he need to wear?

S1: Some comfortable clothes would be best.

S2: Fine. I’ll talk to him and call you again very soon. Where would it be best to meet?

S1: At the studio if that is OK with you. Thank you very much.

S2: My pleasure.
