Marcos: How many brothers and sisters do you have, Mei-li?
Mei-li: Actually, I'm an only child.
Marcos: Really?

Mei-li: yeah, a lot of families in China have only one child these days.
Marcos: I didn't know that.
Mei-li: What about you, Marcos?
Marcos: I come from a big family. I have three brothers and two sisters.
Mei-li: Is that typical in Peru?
Marcos: I'm not sure. Many families are smaller these days. But big families are great because you get a lot of brithday presents.
