<p>It started Saturday morning. I was sitting at my kitchen table and heard "Can you hear me?" in a low whisper. I thought maybe I was hearing things at first, but then I heard other noises clearly - seemingly coming from different parts of the house. It completely freaked me out to the point that I was convinced someone was in my house. I got up and went from room-to-room with a knife (as if I would even know what to do with it) - even kicking open doors in the process. I found nothing, the noises continued every 30-40 minute or so...</p>
<p>After the initial freak-out, I thought about how my friend had been over the night before. This particular friend has a long and storied history of getting great enjoyment from messing with people (me in particular) - and planting something in my house would be right in his wheelhouse.
At this point I've convinced myself that he planted something - but I wasn't about to call him and give him the satisfaction of knowing the degree of mental anguish he had caused me - so I started looking. I tore my house apart looking for whatever he planted and COULD NOT FIND IT. Drawers, shelves, heavy furniture, everything. </p>
<p>It was impossible to locate because the sounds seem to come from everywhere. Luckily it was too quiet to hear in my bedroom so I just went to sleep, determined to find it the next day after work.
But I didn't...</p>
<p>The next 3 days consisted of me doing the same thing every night to no avail - until I finally found it last night. It was magneted to a screw head on the underside of my dining table. I knew he was a frequent purchaser from that web site so I browsed around there until I found this device.</p>
<p>This brings me to today - I've not told him anything, nor have I even seen or talked to him this week. I can't possibly give him the joy that will come with knowing how effectively he's ruined my week. He will NOT get the pleasure of telling all of our friends about this while laughing maniacally. I need to turn the tables on him, and I need your help.</p>
