They are strange creatures, humans. They like to get wet, for a start, and they even have a special room to get wet in; the bathroom.
In the bathroom, Rachel left this on a little dish beside the bath. She keeps saying it's nearly finished, and that she must buy a new one. We looked at that little dish with interest.
Sometimes Rachel leaves tasty morsels lying around on little dishes. This one looked a bit like cheese.
We decided to conduct a scientific experiment, and taste it.
Big mistake this time. Nasty! And definitely not cheese!
Rachel found a little bit that we spat out, lying on the floor. She laughed a lot, and thought of this:
We decided not to say which of us conducted the experiment; cats don't like to be laughed at.
And anyway, it might have been cheese; we have to take risks in the name of Science, you know.
