M: Are you also from Bethel Middle School
W: Yes. I’ve been studying there for three years.
M: Well, I really can’t believe not having seen you there all these years.
W: You see, I hardly stay in school after class. I have to rush to my music teacher’s place to practise the piano.
M: Does it mean you want to be a musician
W: I really don’t know, but that’s certainly what my parents expect me to be. What about you
M: Like my dad, I want to be a doctor. But he never had the chance, so he places his hopes on me. I know it’s not easy to study medicine. Guess I’ll have to work real hard.
