The other side of learning is forgetting,
How can you open your eyes if they don't close?
Teachers find this very upsetting,
They like you to be always on your toes.

Anybody can see that x equals y,
When it is written in white chalk on a black board,
Just as anyone can see that a black cloud in a blue sky,
Means that rain is going to fall.

Tidy children are good, untidy children are slatterns,
Everything is labelled according to looks,
But beneath our lids spring
rainbow-coloured patterns,
That were never found in books.
