Nick: Hi Mi, welcome to our house! 

Elena: Come upstairs! I’ll show you my room. 

Mi: Wow! You have so many dolls. 

Elena: Yes. My hobby is collecting dolls. Do you have a hobby? 

Mi: I like collecting glass bottles. 

Elena: Really? That’s very unusual. Is it expensive? 

Mi: Not at all, I just keep the bottles after we use them. What about doll collecting? Is it expensive? 

Elena: I guess so, but all of my dolls are presents. My parents, and my aunt and uncle always give me dolls on special occasions. 

Mi: Your dolls are all very different. 

Elena: Yes, they’re from all over the world! 

Nick: I don’t know why girls collect things. It’s a piece of cake. 

Mi: Do you have a difficult hobby, Nick? 

Nick: Yes, I enjoy mountain climbing. 

Mi: But Nick, there are no mountains around here! 

Nick: I know. I’m in a mountain climbing club. We travel to mountains around Viet Nam. In the future, I’ll climb mountains in other countries too.
