I think this would be great for a divorce or a breakup greeting card:
We had some fun times while we were together
And many of those moments I’ll always treasure.
But I have to let you know just how I feel,
My muse has been crushed under your unappreciative heel.
So I’m freeing myself from your oppressive ways;
I hope to never see you for the rest of my days.
I’m sure losing you will improve my luck,
And from this day forward may your entire life suck.
Goodbye!
