Dear Peter,

I am terribly sorry that I couldn’t practise spoken Chinese with you this time. I should have told you in advance , but something happened beyond my expectation . My teacher called me to send his computer to his office. Unfortunately, my mobile phone got a flat battery after I received the call . Worst of all , I was caught in a traffic jam on my way back.

Next Saturday afternoon , I’d like to meet you at three o’clock at the gate of the park near our college. We will talk about Chinese table manners . You may as well make some preparations in advance if possible.

Once again , I am sorry for any inconvenience caused . Hope to see you soon .

Yours
