You seem to hear a soft, echoing sound coming from one of the taps in the corner of the room. If you take a step closer to the tap, you'll notice that it's getting louder....and louder....and louder, until the echoing sound is clearly one long, loud, heart-wrenching moan.

Hmm, who - or what - could possibly be making such a lonesome sound? And how is the sound coming from inside the facet? Turn it on and maybe you'll see.
