A scenario:
An old man lying in bed, dying, making one last desperate effort to recall at least one memory that justifies his having lived. As the last seconds draw close, he suddenly remembers the one woman he has loved - and though she never loved him, he sees that she did give him a gift that added value to his life. She helped give birth to love in his heart by her very existence.

How would you write of it? As a poem or a short story? (I have no intention of writing it, just asking)
