I don't think this is my best, but I'll see what everyone else thinks.

One World

I hear a baby crying
A sad sound, a lonely sound
I want to take her in my arms
And then I dry away all her tears

Lately everything had been going bad for Zuko. But right now him and his uncle were at a market getting some supplies. Uncle Iroh heard the singing and insisted on going to listen. They got to the inn that the singing was coming from and went in. Zuko rather unwillingly.

I see a boy, who's frightened
A young boy, with old eyes
I long to say 'You're welcome here,
You can be happy now that you're warm'

The girl singing was in the front of the room, which had quite a few people in it. Iroh and Zuko stayed in the back. The girl had brown hair and eyes. She was wearing a green kimono. Her voice was beautiful and Zuko found himself listening to the song.

We're all a part of one world
We all can share the same dream
And if you just reach out to me
Then you will find deep down inside
I'm just like you

Loud voices raised in anger
Speak harsh words, such cruel words
Why do they speak so selfishly
When we have got so much we can share?

So let your hearts be open
And reach out with all your love
There are no strangers now
They are our brothers now
And we are one

Zuko thought back to Lee, Song, and the Avatar… no Aang. He thought about how the water tribe girl offered help to his uncle recently. He had been too upset to realize that she might be able to help… He thought back to an offer of friendship he had refused.

We're all a part of one world
We all can share the same dream
And if you just reach out to me
Then will find deep down inside
I'm just like you

We're all a part of one world
We all can share the same dream
And if you just reach out to me
Then will find deep down inside
I'm just like you

I'm just like you

The song ended and they left. While they were walking down the street Uncle Iroh said, "Beautiful song wasn't it?"

"Yes, Uncle it was."
