People don't talk like this, theytalklikethis. Syllables, words, sentences run together like a watercolour left in the rain. To understand what anyone is saying to us we must separate these noises into words and the words into sentences so that we might in our turn issue a stream of mixed sounds in response.

We are so used to the notion of our own inevitability as life's dominant species that it is hard to grasp that we are here only because of timely extraterrestrial bangs and other random flukes.

By the time I had finished my coffee and returned to the streets, the rain had temporarily abated, but the streets were full of vast puddles where the drains where unable to cope with the volume of water. Correct me if I'm wrong, but you would think that if one nation ought by now to have mastered the science of drainage, Britain would be it.

It is a talent we have only barely begun to grasp.
