The word that summed up Bob’s day was ‘LITTER’. He was sitting in bed in the dark. His wife was asleep beside him and he had only his own mind to explore. As he rummaged around in his day’s thoughts he noticed all the discarded wrappers that had packed his best ideas and that now lay like litter cluttering up his inner world. It was just like his office, he thought. Or his car. Or his computer – especially his computer, where the litter had proliferated to such an extent that he could no longer keep track of all the folders and sub-folders and favourites and websites and images and snippets of word and sound and clips and software. As he lay there thinking he realised, he had so much litter that he had lost all the good ideas that had been inside the wrappers.
