U-Turn; or, The Learning Curve

Oh, deary me! Oh, what a shame!
No doubt the weather is to blame,
And teachers, and the Whitehall crew,
And probably a spad or two -
Who have not done enough, I fear,
To help me with the Twittersphere.

I signed the Bible, full of pep,
Yet now I'm on the naughty step!
But children, future of the nation,
Fear nothing for your education.
You need not worry. Even now,
I'll screw your schooling up somehow.
