When Goldilocks Came To Our House

Once there was a little girl with curly blonde hair who was running away from some very grumpy bears. She happened to come across a house on the edge of town and, noticing that the door was open, she decided to hide inside until the bears had calmed down a bit.
As she hid inside the house, she realised that she'd left her shoes in the bear's house. Looking around she saw three pairs of freshly-cleaned football boots lying on the floor. Unfortunately the little girl hadn't learned anything from her earlier escapades, and decided to try on the boots.
First she tried on the white pair. 'Oh no, she said, 'These are far too tight, and the colour is all wrong'. Then she tried on the biggest pair. 'Oh these won't do at all!' she exclaimed. 'The moment I put them on I could feel any footballing talent drain out of me and I know that I'd utterly useless wearing these!'. And then she tried on the middle-sized pair. And they were a perfect fit. Delightedly she skipped out into the garden and started curling shots into the top corner of the net. She was so pleased with her new-found skills that she didn't notice the bears sneaking into the garden...
