Chen Ping: Hi, Ben. Would you like to go to the zoo with me on Saturday morning?
Ben: I’m sorry I can’t. I have piano lessons every Saturday morning.
Chen Ping: OK. Who’s your piano teacher?

Ben: My mother! She’s good at playing piano.

Chen Ping: Wow, your mother is great!

Ben: Yeah. I’m really proud of my mother.

Chen Ping: Do you want to be a pianist when you grow up?

Ben: I think so and I still need more practice.
