Here in a Rocky Cup by Edna St. Vincent Millay

Here in a rocky cup of earth The simple acorn brought to birth

What has in ages grown to be

A very oak, a mighty tree. The granite of the rock is split

And crumbled by the girth of it.

Incautious was the rock to feed The acorn's mouth; unwise indeed

Am I, upon whose stony heart

Fell softly down, sits quietly, / The seed of love's imperial tree

That soon may force my breast apart.

"I fear you not. I have no doubt My meagre soil shall starve you out!"

Unless indeed you prove to be

The kernel of a kingly tree;

Which if you be I am content To go the way the granite went, / And be myself no more at all, / So you but prosper and grow tall.
