W: Hello, Simon. I haven’t seen you for a long time. I heard that you’d gone for a trip.
M: Yes. I’ve been back for two days.
W: How is your travel?
M: Wonderful! It seems more and more people in our country like traveling. And when I was traveling, I met many people doing the same thing.
W: Yeah, how many countries did you visit?
M: I went to Singapore first, and then I traveled around the European countries, such as France, Germany, and Greece. England is also on my schedule; however, I had to fly back to attend a very significant conference.
W: Great! It must be an impressive experience. So how long did you stay in Singapore?
M: I arrived there on Monday, and I planned to stay there for one week. But I left for Europe two days earlier.
W: What about Singapore? People say it’s very, very modern, but because it’s so modern, it’s rather boring. Did you find that?
M: Um, well, it’s difficult to say really. It has different attractions, you know, the Chinese, Malay and Hindu communities are there. It has its own culture and custom, very different from the European countries, and it’s a great big shopping center, and I really enjoyed it from that point of view. And it was very clean.
W: Really? That’s great! I will fly there for shopping next vacation.
