George Boleyn had a woman
And he was in love with Francis Weston
As you are in love with Henry VIII
As I am with my history teacher
Watch us!
Prancing around court
Me married off at twelve
Having a man twice my age
With not a care in the world
You watching over me
Like an older brother
Henry doesn’t look like he does on The Tudors
You might as well admit that he was fat
That he ought to be the one with child
And not Anne
I’m fertile enough now
And your Francis Weston doesn’t love you back
Like I do

Something about the wording of this poem doesn't fit with me. Mind you, it's not the beat, it's the wording, so read it aloud and make sure everything sounds right to you. You seem to have quite a knack for this poem thing. Also the back story behind this poem is, I suspect, historically correct, so I assume that you have a knack for that too. The problem is that it's too short, and since it's so short, I don't have much to review.
But nice work, and keep writing.
