Dust of Snow

      by Robert Frost


The way a crow

Shook down on me

The dust of snow

From a hemlock tree


Has given my heart

A change of mood

And saved some part

Of a day I had rued.
I sometimes use this poem in my haiku workshops to show the difference between objectivity (first part) and subjectivity (second part). Haiku tend to aim more towards the first part of this poem (minus The way), and seek to trust the image.
