My wife and I use to have an old couple living next to us in an apartment a little while back. I was working 3rd shift at the time so of course I stayed up all night every night. Anyhow it was a night off, and I was on the computer while my wife was sleeping. About 5am I went to use the bathroom and noticed the carpet was wet. I couldn't figure it out at first because this hallway was in the middle of the apartment. I went to the other bathroom which was on the other side of this hallway through a huge walk in closet. The floor was even worse, it was completely soaked. I went through to the bathroom and heard water running. I thought it was a pipe or something. I went outside to see if I could hear through the neighbors bathroom window since it was right next to mine. I hear the shower running. Their light was even on in the bathroom. I banged on their door and no one answered. I thought something happened to them as they were both very old.
So next I had to deal with trying to communicate with the security guard who didn't speak English at all because we lived in Miami! So finally someone drove though the gate that spoke some english and we were able to get the emergency maintenence number from the guard. Needless to say, "emergency maintenence" wasn't picking up the phone of course.
So we called the police. Now we had 4 police cars their banging on these peoples door and window with their keys. Finally the old man came out in his kitchen. After the police got the kitchen window open. I bet he was scared thinking people were breaking in. Anyways, so they left their shower on and flooded our place very badly and we had to have someone come out to shampoo the carpet and such so it wouldn't stink.
The sad part was it happened again from this same apartment.
