Speaking
CLB5S Invite a friend, co-worker, or classmate to lunch.
Record your conversation with your partner on Chirbit.com, indicating who are speaking.

First greet each other.
Partner A invites Partner B to a lunch on Saturday. B says no and gives a reason, but invites A to lunch the following Saturday. A agrees but wants to understand some detail that is not clear about the lunch (e.g. who all will be there, going dutch, time, venue).
End the conversation in a friendly way, and record it the other way as well--i.e. Partner B starts by inviting A to an event on Saturday.
A:hello, partner B,could you please come my house for a lunch on Saturday.
B:It's very sorry. This weekend I have to see doctor  for  my son's eyes. But , I want to invite you to have a lunch together next Saturday. could you please come?
