There are four sentences in each of the three parts of children's poetry.

The wind is coming.

No one has ever seen the wind.

Needless to say, I support you.

But when the willows dance happily,

We knew the wind was coming.

No one has ever seen the wind.

Needless to say, I support you.

But when the grass nodded to us,

We knew the wind was coming.

No one has ever seen the wind.

Needless to say, I support you.

But when the red flag is flying in the air,

We knew the wind was coming.
