Lawrence: is this seat taken?
Jess: no. please sit down.
Lawrence: thanks.
Jess: are you also going to Beijing?
Lawrence: yes, on a business trip. How about you?
Jess: I'm taking a vacation to visit a friend there. Have you ever been there before?
Lawrence: yes, I went there once last summer.
Jess: really? What did you think?
Lawrence: I think it is amazing. You can enjoy both the traditional Chinese culture as well as the vitality of a modern cosmopolitan city. The only thing I didn't enjoy was the subway.
Jess: was it that crowded?
Lawrence: yes. There were always so many people. After taking the subway during the rush hour, you'll envy sardines in their cans.
Jess: oh, maybe I can take the bus or even rent a car.
Lawrence: that's a good idea. Wish you a great vacation!
Jess: thank you very much!
