Well I naively opened the door and told her to come in while holding my pistol at low ready with one in the chamber. I immediately shut the door and locked it behind her, and noticed a couple of things. 1. She didn't appear to be scared or uncomfortable and I was holding a pistol and only wearing boxers 2. Her appearance/ clothes were "ghetto" for lack of a better word. She was wearing a large coat asit was winter and cold outside. So I told her to take off her coat and have a seat on the couch. She proceeded to tell me she had broke down in the neighborhood and was tired and thirsty and needed help. She asked for a glass of water and asked if she could have a smoke. I instructed her to get a glass and pour herself a glass of water and asked why she was smoking if she was pregnant. She went on to tell me her "Doctor" told her it was ok to smoke while pregnant as long as she smoked "light" cigarettes. I called my wife and told her what was going on and asked her to come home and watch the kids so I could give this girl a ride home. I warned her to approach carefully and drive away if she saw anybody outside. When my wife got home I handed her the loaded pistol, got dressed and told her not to answer the door or let anybody in until I got back. While driving this girl home I didn't see a broken down vehicle, and she asked me for money before dropping her off in front of a trailer park. I got home safe and my wife returned to work and everything ended up ok that night.Now that I am older and have my chl and more situational awareness I realize what a fool I was to open the door, and how badly I mishandled situation. At the time I didn't know what section 8 housing was, and didn't realize how much drug activity and crime happens in that area. A couple years later a kid was shot and killed in the middle of the day in the alley behind that duplex/house.I figure the girl was probably a prostitute and likely a drug user and god knows what else. She was probably casing the house for a boyfriend waiting outside or setting me up for a home invasion type situation, or at the very least trying to get away from police or escaping from some other sketchy situation. I am lucky nothing bad happened and realize how lucky I am that God was watching out for my family that night. I realize I made multiple bad decisions that night and handled the situation like a clueless idiot. The only thing I did right that night was having my weapon with me and ready and not dropping my guard completely just because the pregnant young girl didn't appear to be a threat. I would like to hear feedback and would like to know if anybody else has had a similar experience before getting their chl. Feel free to critique the incident but please don't be too harsh lol...
