A Water Situation

Just as I was finally dropping into sleep this morning, I heard my cell phone ring. While I am generally able to distinguish between the different ring tones I've selected for various tasks, I immediately assumed that it was 8:50 a.m. and that my alarm was going off.
Not so.
I had the presence of mind to actually check my phone (as opposed to one of my roommates who had simply canceled the call after she, too, mistakened it to be an alarm) and realized it was an unfamiliar 949 number. The number for the leasing office, as it turns out.
In my bleary-eyed and barely awake condition I only registered snatches of the conversation that followed. Certain key phrases like: "need to shut off the water for your building" and "there's been an emergency in an apartment."
The news jolted me awake and I was lucid enough to ask both "Right NOW??" and "For how long??" To which the answers were "Yes" and "two hours." I hobbled out of the living room to inform the rest of my roommates, even as I managed to thank the leasing office representative for giving us as much notice as she could.
One of my roommates was in the shower, so I quickly shouted for her to rinse off immediately because the water was going to be shut off. Then I scrambled to wash my face and fill a cup of water to brush my teeth with later.
This may explain the loud hammering sounds that began around 7 a.m. Clearly something went wrong with the piping. I just wonder what problem could have been so severe as to force the leasing office to shut off water in the entire building with only a scant minute's notice. For two whole hours, as the prognosis ran.
We'd better be talking about major flooding here, folks.
And now I have to get ready for class. I fully intend to return directly and nap afterward.
