Here is her Another Valentine. It is much funnier than the poem I learnt for A-Levels (which wasn't that profound anyway. How do they expect us students to write essays on things that aren't profound or full of meaning?)
The rhyme scheme is abaaabaa. I won't post a long commentary since it speaks for itself.
Today we are obliged to be romantic
And think of yet another valentine.
We know the rules and we are both pedantic:
Today's the day we have to be romantic.
Our love is old and sure, not new and frantic.
You know I'm yours and I know you are mine.
And saying that has made me feel romantic,
My dearest love, my darling valentine.
