Waterfall

My little daughter paints all the time while her color pencils and crayons are all around her.
Some days ago she wanted to explain about what she was planning to paint for me.
I asked her,'' What do you want to paint?? ''
She said," I want to paint a mountain with a lake pouring from it. "
I asked her," What kind of lake pours from the mountain? "
She brang up her head and said," that kind of lake which is in the middle of two mountaines...
After a little thought I understood and said,"Oh, I see, you mean a waterfall, don't you?
Suddenly, she understood and said," yes, yes, that's it, It's a waterfall.
