Sung. In 1972, when I was, um maube seven years old, the President of the United States, President Nixon came to my country, came to China. And one of the places he visited was Datong, which was my city. And I was very good at dancing when I was young so I was chosen from my school to dance, to dance in front of the President. And at the end, we were all standing in line and he stopped when he came to me and I remember he smiled and said `Hello`, which was the only English word I knew. And I just said `Welcome`, in Chinese, or course. I still remember it very clearly.

Andy. I met my girlfriend while I was working as a barman in a disco. And there was this really gorgeous girl in the club and I really wanted to talk to her, but I couldn`t because I was working. Anyway as luck would have it, I was carrying a ... a bucket of ice and I dropped it, accidentally, or course, just next to where she was sitting. And well, I said `Oh, I`m so sorry. I`m really, really sorry.` And we started chatting and I found out her name was Karen, and in the end she gave me her phone number. We started going out and we`ve been together for nearly two years.
