Emily: Hey, Misha, Rob, Mark! Look who's coming! It's
my grandma, Olga. She's the most interesting
person I have ever met.
Olga: Hello, Emily. Hello, boys. It's nice to meet you.
Misha:You have a Russian name. That's interesting.
Olga: I am Russian. My parents came to America many
many years ago and brought me with them. I was
only a little girl, but I remember the first thing I saw
in America from on board the ship.
Rob: It was the Statue of Liberty, wasn't it?
Olga:Yes, it was. Every time I see it I get tears in my
eyes. But you've seen it yourselves, haven't you?
What do you think?
Misha: Well, to be honest... it looks great, but...
Mark: Yes, it's one of those big American symbols which
nobody believes in any more.
Rob: Everything we saw in New York is about money: all
of those skyscrapers, built by rich people and big
corporations. And there are still so many poor
people in the streets... Is that liberty?
Olga: Well, there must be some place you haven't been
to yet in the city. I could go with you and show you
something that you haven't seen.
Rob: What's that?
Olga: How about the Rockefeller Center?
Misha: But we've already been there.
Olga: Let's see it again!

Olga and the friends arrive at the Rockefeller Center.

Olga: Look at this building again, children. What do you see?
Misha: I see a very big building which was built by somebody who had so much money that he didn't know how to spend it all.
