Hope is the thing with feathers

That perches in the soul,

And sings the tune - without words,

And never stops at all,

And the sweetest in the gale is heard;

And sore must be the storm

That could abash the little bird

That kept so many warm.

I’ve heard it in the chilliest land,

And on the strangest sea;

Yet, never, in extremity,

It asked a crumb of me.
