W: John! How are you? It’s been ages since we met last time!
M: I’m fine, thank you! Seeing you now just reminds me of the good days we spent together in school.
W: Me too. You look more energetic than before. What are you doing these days?
M: Believe it or not, I’ve just opened my own restaurant. I’m also head chef.
W: Are you kidding me? You’ve always hated cooking!
M: Well, I used to hate cooking, but now I really love it.
W: I just can’t believe my ears! When did you change your mind?
M: After I tried Chinese food. It was so delicious and quite different from any food I’d had before. Before that, I used to cook really boring things for my family. But now the whole family enjoys the Chinese food I cook for them. Cooking is really the most enjoyable work to me.
W: I still can’t believe it! So, did you go to cooking school or something?
M: Yeah. I went to Beijing to study. The teachers there were excellent and I learned a lot. That’s of great help to my restaurant.
W: Really? How long did you stay there?
M: I was there between 1997 and 1999.
W: And what did you do after that?
M: Then I came back here. I worked in a Chinese restaurant for about two years to get some experience.
W: That’s great! So, where is your restaurant? I’m going to eat there this weekend!
M: It’s right on the comer of Queen’s Street. I’ll be very happy if you come.
W: OK, I’ll be there with my husband on Sunday.
M: I look forward to seeing you, bye-bye.
