Over the summer I was fortunate enough to obtain a kitten - who at this very moment is trying to walk all over my keyboard - from a colleague whose cat had recently had a litter. In true maths teacher form I decided to name her Pi, Paella for long or 'Oi stop scratching the carpet' depending on the scenario. The teacher whose cat it was has a daughter in year ten who was in tears when I took the kitten away. I can now say that I made a pupil cry, though it's perhaps not such a thing to be proud of.

This afternoon one of my year tens, who for the record I've yet to make cry, informed me that my cat isn't called 'Pi', she's 'Mini', which might mean that she was once a British icon but is now manufactured by BMW. Apparently one of her friends had wanted that particular cat and had chosen the name for her.

Tough.
