Hi!

How are you?

I'm good!

That's beautiful!

Thank you so much.

Karolina, what is your last name?

Protsenko.

Protsenko.

And so you have been playing since how old?

How old were you when you started?

When I was six.

Six years old.

And what made you be drawn to the violin?

I just wanted to play an instrument.

And my parents asked me, what do I want to play?

A violin or a flute?

And I just picked violin without knowing what it was.

[LAUGHTER]

And you must practice a lot.

How often you practice?

Every day, two to three hours.

Wow.

That's why you're that good.

And then you dance around.

It's so entertaining.

And then you're on the streets--

the promenade, right?

In Santa Monica.

Do you love that?

Yes.

Yeah?

Do you make a lot of money?

Are people very generous?

Yeah.

Oh, that's good.

[LAUGHTER]

That's why you go out there, right?

What are you gonna save up for?

What do you want to do with your money?

I'm saving it for college.

And I really want a puppy, but I don't have a house.

My mom said when we're gonna have

a house and a big backyard, then I might have a puppy.

Yes, and time for a puppy, 'cause puppies take a lot--

also, there's a lot of dogs that look like puppies that

a little older, and they don't act like puppies.

'Cause puppies are a lot.

They chew on furniture and they pee in your house.

[LAUGHTER]

Just to let you know.

All right, well, I got you something

for the next time you perform.

Bring it out?

OK, so there you are.

Thank you so much!

Thank you!

Oh, you're welcome.

And then I got--

[APPLAUSE]

It's amazing.

Yeah.

See what I have in my--

here's some of your first cash for your tip, OK?

Thank you so much!

[CHEERING]

All right.

We'll be right back.
