Shower

The water blasted into his face like a million needles jabbing at him.
He needed to adjust it so it was less painful.
He twisted the shower head and the water came out in one thick jet, the strength of which stripped two tiles from the wall behind him.
He quickly twisted it the opposite way, expecting the spray to become finer. It didn't.
The water came out faster than before and the shower head took on a life of its own, thrashing around wildly. It tore more tiles from the wall and cracked the glass door.
He leapt out of the shower and went to turn the water off at the mains as his bathroom was destroyed.
