The Lockless Door-Robert Frost
It went many years,

But at last came a knock,

And I thought of the door

With no lock to lock.


I blew out the light,

I tip-toed the floor,

And raised both hands

In prayer to the door.


But the knock came again.

My window was wide;


I climbed on the sill

And descended outside.

Back over the sill

I bade a 'Come in'

To whatever the knock

At the door may have been.


So at a knock

I emptied my cage

To hide in the world

And alter with age.
