My parents have a friend of their (my brothers X girlfriend) watching their house while they are out of the country. My wife called over there and a guy answered the phone and hung up on her when she asked for this girl. When I got home from work I called and damit, the guy hung up on me. I was concerned for the girl and my parents house, so I rolled over there with my carry pistol (concealed). I opened the front door (locked) and it was silent. The girls car and my parents car were all there so I figured someone was in the house. Nothing looked out of place so I scanned the doorway, corners and went to my dads room slowly and quietly to check his safe. It was fine so I creeped out through the hallway to check the other rooms and I saw a guy with green hair laying in my parents guest room with his eyes closed. I kept one eye on him for about two minutes and confirmed he was sleeping (more like passed out). At this point, I did not want to confront the guy since all I could see was his head because a blanket was over him. No other sounds in the house. I slowly backed up and went out back to contemplate. What the hell do I do? This guy could know the girl watching the house but for all I knew she was tied up in the closet. Since one person could not effectively clear a 4 bedroom house, I called 911. The cops were there within 2 minutes (wow). They searched me and locked my Glock up in their car, then asked me where this guys was. The 3 cops cleared the house and cuffed this guy (who was naked) and sat him in my parents office. It turns out he was this girls NEW boyfriend whom I had never seen before. The girl was out with another friend at the time. When I asked him why he hung up on me he said because he was "sick", he insisted that he knew my parents etc... I had the cops escort him to the street and sent him hoofing. For a while, I thought that I over reacted by calling the police. But given the unknowns, I am glad I did. I am now watching my parents house.
