WHY???

So I went to take a nice happy warm shower this morning, figured it would help clear up my nose a little and warm me up as my room is FREEZING thanks to drafty windows and a cold breeze, only to discover that
THERE IS NO WARM WATER.
At all. Zero. Zilch. Nada.
I stood there with my hand in the shower, the faucet all the way on the warm side, for about a minute or two and all that happened was that my hand went numb because the water is that frigid.
That was ten minutes ago. My hand is STILL cold.
*shakes fist at sky*
I WANT A SHOWER!!!!
:P
