"I spend many hours each day playing with sentences. I regard each sentence as a little wheel, and my ambition lately has been to gather several hundred of them together at once and to fit them all end to end, with the cogs interlocking, like gears, but with each wheel a different size, each turning at a different speed. Now and again I try to put a really big one right next to a very small one in such a way that the big one, turning slowly, will make the small one spin so fast that it hums. Very tricky, that."                                                                                     – Roald Dahl
