The show was in the best. Oh boy! He was exited but something shivered the wall so hard that he suddenly woke up from his enthusiasm; he left on the center table his 4th beer and walked to the wall, but before he reached it the wall shivered again with such a thump that his shoulders leaped back and his eyes got lose in a abyss of doubt.
First he thought that his neighbor was getting hit, or maybe somebody fell.
When the nerves where gone; he decided to take some snacks from the kitchen and more beer (if he was hearing because of the beer then he was going to make a party in his head). In his way to the kitchen a scratch followed him from inside the wall; now he was unquiet, and the green rosettes in the wallpaper seemed to be spinning, so curiosity had won to fear, and he drew near to the wall.
He heard a smooth growl.
Next morning the wallpaper had some burns, nails and blood as if somebody fought to not be swallow by the wall.
Indeed! A beautiful wallpaper got wasted.
