Hello, Miao Li, Where are you going?
Hello, I am going to the store to buy some fruit.
Oh, Would you do me a favor?
Yes?
Please mail this letter for me on your way to the store.
Sure. Do you want it to be registered?
Yes, I think so. There are some pictures in it. It would be a great pity if they were lost.
Yes, I will be glad to mail your letter.
Thanks.
