My friend was supposed to pick me up from the airport, but she just called me and said she is stuck in traffic downtown so she won't be here right now. It's 11 now, so there is no way I'm going to the restaurant at 11:30 as we planned. I wonder if we could reschedule our appointment to sometime this afternoon

We had planned to meet at about 11 a.m. Since you can't make it, let's reschedule our appointment at 1:00 pm. (C) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (D) M: OK, let's postpone our meeting for half an hour. Can we meet at 2 p.m?
