Rubbish Monks

Rudiger Bigglestone ambled down the street on the way to work, dropping his chocolate wrapper on the floor without a second thought. He was about to turn the corner when a barely audible *swish* caused him to turn around. The street was empty - and the wrapper gone. He thought nothing of it and continued on his way.
During lunch break, some sandwich packets were added to the general detritus of the city floor - and an empty chip packet and a soft drink can by dinner time. Each time Rudiger turned - he was greeted by the retreating form of a small person turning a corner, or vanishing into the crowds.
The buzz of his alarm roused Rudiger from the warmth of sleep, he clambered shivering out of bed, and drew back the curtains. Glancing downwards, he saw that his garden was littered with...well...litter. It must have been those bloody kids - honestly they have no respect!
Leaving again for work, Rudiger kicked the litter out onto the pavement - the bin men would probably pick it up - after all, it is their job. A low pitched muttering was heard, but on turning he found just an empty street.
The next morning, Rudiger wakes to a garden with even more rubbish obscuring it, starting to get angry he runs outside and kicks the rubbish onto the road. He goes back inside and is about to close the door when the grumble reaches his ears again. He leaps back out the door and searches through his hedge, dragging out a little wizened old man by the scruff of his neck. The man is dressed in a simple brown robe and is carrying a broom in one hand and a bag in the other - labelled "Rudiger Bigglestone". "What are you doing!?" Rudiger yelled, exasperated. "Everything has it's rightful place" Spake the monk, "You just needed to be taught". With that profound statement, the monk strolled into the morning mist and was gone.
