Plumbing Problems...Not Me, My House

OK, here's a problem I did not need today! I was using the bathroom, a pretty frequent experience around here. I accidentally knocked my hair dryer off the vanity, and all the sudden all hell broke loose! A pipe apparently came undone inside the wall and away from the shut off valve. Good grief! I don't need this, so I had to "run" downstairs to the main shut off valve to the house, eek!!! Called my brother, called my landlord, called a plumber. So now I am waiting patiently for the plumber to come over. This is not a good situation for me today! If ever I needed the plumbing to be in good working condition, this is the day! Calgon, take me away!
