In my present confused state I thought I had better have a shower only to be confronted by the fact that my wife had moved the position of the shower head. It took a while for this to sink in, and then I thought Oh Well! And pressed the button. This is where my latest invention " The Shower Brolly" would have come in handy, deployed within seconds the shower brolly will protect the unsuspecting user of the shower/ water cannon from freezing cold or scalding hot water whilst they try to reach the control knobs. As it was I haven't made one yet and had to face a freezing cold jet of water directly aimed at me whilst I tried to reach the spray head to deflect it away.
My wife thought it was hilarious!
