AHi Anna, come in.
BWow, your apartment is a mess.
AIt's very nice of you to invite me.
BI'm very glad you could come, Mr. Liu. Will you take a seat at the head of the table? It's an informal dinner, please don't stand on ceremony... Mr. Liu, would you like to have some chicken?
AMom, I just finished my paper. Can you proofread it before I hand it in？
BSure, let's take a look. Sweetie, this is terrific. Your ideas are so original.
