“Spring” by Edna St. Vincent Millay

To what purpose, April, do you return again?
Beauty is not enough.
You can no longer quiet me with the redness
Of little leaves opening stickily.
I know what I know.
The sun is hot on my neck as I observe
The spikes of the crocus.
The smell of the earth is good.
It is apparent that there is no death
But what does that signify?
Not only underground are the brains of men
Eaten by maggots.
Life in itself
Is nothing,
An empty cup, a flight of uncarpeted stairs.
It is not enough that yearly, down this hill,
April
Comes like an idiot, babbling and strewing flowers.
