In fact what he was really looking out for when he stared distractedly into the night sky was any kind of flying saucer at all. The reason he said green was that green was the traditional space livery of the Betelgeuse trading scouts.

Ford Prefect was desperate that any flying saucer at all would arrive soon because fifteen years was a long time to get stranded anywhere, particularly somewhere as mindboggingly dull as the Earth.

Ford wished that a flying saucer would arrive soon because he knew how to flag flying saucers down and get lifts from them. He knew how to see the Marvels of the Universe for less than thirty Altairan dollars a day.

In fact, Ford Prefect was a roving researcher for that wholly remarkable book The Hitch Hiker's Guide to the Galaxy.

Human beings are great adaptors, and by lunchtime life in the environs of Arthur's house had settled into a steady routine. It was Arthur's accepted role to lie squelching in the mud making occasional demands to see his lawyer, his mother or a good book; it was Mr Prosser's accepted role to tackle Arthur with the occasional new ploy such as the For the Public Good talk, the March of Progress talk, the They Knocked My House Down Once You Know, Never Looked Back talk and various other cajoleries and threats; and it was the bulldozer drivers' accepted role to sit around drinking coffee and experimenting with union regulations to see how they could turn the situation to their financial advantage.

The Earth moved slowly in its diurnal course.

The sun was beginning to dry out the mud Arthur lay in.

A shadow moved across him again.

"Hello Arthur," said the shadow.

Arthur looked up and squinting into the sun was startled to see Ford Prefect standing above him.

"Ford! Hello, how are you?"

"Fine," said Ford, "look, are you busy?"

"Am I busy?" exclaimed Arthur. "Well, I've just got all these bulldozers and things to lie in front of because they'll knock my house down if I don't, but other than that ... well, no not especially, why?"

They don't have sarcasm on Betelgeuse, and Ford Prefect often failed to notice it unless he was concentrating. He said, "Good, is there anywhere we can talk?"

"What?" said Arthur Dent.
