Wing-Sprouts

It happens when the birds go by
And leave you far behind;
And you flutter, till you ache
All around your mind.--
Like a Flag,
Like a Flag
Flapping at the wind!

It happens when you catch the hills
As blue as yesterday;
You hold your heart in both your hands,
Or it would fly away.
Yes, it would!
Yes, it would!
Away--away--away!

It makes your heart into a Bird
That darts, and leaps, and sings.
--Oh, feel my pinafore, high up!--
Oh, do you think it's Wings?
Do you think--
Do you think--
Oh, couldn't it be Wings?
