Next morning, they are walking to Central Park. There are a lot of people. Mi-na and David walk around for about an hour and then they take a short rest.

David: Central Park is a great place. There are swimming pools, open-air restaurants and more. But it can also be very depressing.

Mi-na: What do you mean?

David: Mi-na, did you see all those people sleeping on benches?

Mi-na: Yes. Why do they sleep there?

David: Well, many people have nowhere to go and in the summer, they sleep out in the open.

Mi-na: I see.

David: Let's go home and get ready for our trip to Columbia University. It's one of the oldest universities in the U.S.

Min'a trip to New York was fun. She saw many interesting things and met a lot of people. It's always exciting to get to know a new culture.
