Eric       : So where are you from, Carmen?

Carmen : I'm from San Juan, Puerto Rico.

Eric       : Wow, I've heard that's a really nice city.

Eric       : Is it expensive there?

Carmen : No, it's not very expensive. Prices are pretty reasonable.

Eric       : How big is the city?

Carmen : It's a fairly big city, but it's not too big.
