Summary: A fictional adult returns a spare key after a relationship ends, choosing a brief note and a quiet journey home rather than a final argument. Sadness remains. No private or autobiographical event is asserted.

I wrapped your spare key in a sheet of blue,
And wrote the little note I'd promised you.
No long defense, no last attempt to stay,
Just thanks for what we had along the way.

Some doors can close without a slam;
The hurt won't tell me who I am.
I cannot make the old days start,
But I can leave without a hardened heart.

I dropped the envelope and heard it slide,
Then stood a minute by the box outside.
I pulled my collar close against the rain,
And caught the next slow train back home again.

Some doors can close without a slam;
The hurt won't tell me who I am.
I cannot make the old days start,
But I can leave without a hardened heart.
