The other day I was thinking about the world without me.

He was a part of what's good about the world.

They want to learn about themselves and the physical world around them.

When does a child begin learning about the natural world?

He doesn't know anything about the world we live in today.

We have to try to do something about the real world in which children are growing up.

I wasn't just trying to learn something about the world.

So he, the old man, had been wrong about the whole world all his life.

But he did change the way I think about the world.

I am really in love with a lot of things about the world.
