Una Telenovela (For Someone's Sins, But Not Mine)

And I would despair at her
Going, going. I would despair
At her giving, giving, to want

More than she could be giving.
No mother has she, but a woman
She'd be. And I would despair as

If I believed she were me,
And not as I know her to be,
Thrice great, terza rima, more free.
