[...] most people's notion of a cow would perhaps be more like that of the following 10-year-old: 'A cow is a mammal. It has six sides - right, left, and upper and below. At the back it has a tail on which hangs a brush. With this it sends the flies away so that they do not fall into the milk. The head is for the purpose of growing horns and so that the mouth can be somewhere. The horns are to butt with and the mouth is to moo with. Under the cow hangs the milk. It is arranged for milking. When people milk, the milk comes and there is never an end to the supply' (Jean Aitchinson. Words in the Mind. 1997. Page 44)
