I'm not really good at poetry. This was my second attempt at it so that's why it's not too good.
There was a little girl
Who found a big pearl
She kept it in her coat pocket
But it fell and made a racket
Everyone ran after it
While the girl made a fit.
The next day at school
Matt had something cool
It was the pearl, big and shiny
It made the rocks look teeny tiny
And that's how the girl
Lost her precious pearl.
