Thorn in my side

Roses are red,
Violets are blue,
Read on ahead,
If you know what is good for you.

Daisies are white,
Buttercups are yellow,
Time flies,
And feelings mellow.

Peonies are pink,
Ferns are green,
Here is what I think,
You are dead to me.

Roses are red,
Violets are blue,
Dear X,
We are through.

(My first attempt at a snarky poem.)
