Years back (early 70's, way before caller ID and all this tracking technology) my Aunt was receiving prank phone calls where a man would whisper to her, "I am coming to kill you tonite." My Aunt was terrified, so my Father who was a cop and who worked the midnight shift in town, went over to her home to check up on her. He used his key to enter through the side door, walked up the cellar stairs, opened the door to the kitchen to find a loaded shotgun staring him right in the face. It was my uncle who heard that jiggle of the door and thought the footsteps belonged to that threatening caller. Thankfully my uncle who had served in WWII was trained in how to handle a weapon and didnt just shoot. That would have been some tragedy. I am quite surprised my dad who was a cop and who also served in WWII didn't call first. If hebwere alive today I would grill him on that one. Because that could have been some tragedy. My aunt didnt receive another call. The jerk must have moved on.
