You could say that he was the town’s resident graffiti artist.
He daubed his colourful art works all over the place. Some of his pieces were very nicely done and many thought his presentations should be left where they were. To this degree the community showed a certain amount of tolerance every time a new graphic display appeared. Unfortunately, the day came when this budding illustrator went just that tiny bit too far. There are boundaries that should never be crossed. He overstepped the mark the day he embellished the wizard’s wall. It was a large, yellow smiley face. Two big eyes and a wide happy mouth. It was not clear what made him do it. This may never be known. The wizard, being a wizard, only had to pass his hand slowly across the painted sign to instantly learn the identity of the perpetrator. He took particular exception to the image in question on account of the fact that he happened to be an exceptionally serious wizard.
The upshot of it all being that the lad was made to clean the door thoroughly, and he did. No sign of his handiwork remained. On this point, it should be said that all this happened over a year ago and he hasn’t been seen since.
You really shouldn’t mess with wizards.
