I used to have my .40 out on the table partially disassembled whenever a guy I hadn't met was picking my daughter up. I'd put it together while I gave him the rules. Once assembled, I'd put the loaded magazine in and chamber a round while I said, "I feel real sorry for the guy who does something stupid that causes my little girl to get hurt." It's amazing how they called me "sir" after that.
I remember one time, some idiot came to pick her up to go to the movies. He pulls in the driveway and honks his horn. As my daughter is putting on her coat I asked her where she thought she was going. She said, "My date is here." I told her she wasn't going to walk out to his car she'd have to wait for him to come to the door. He just sat out there in his car honking the horn. I told her to sit down and I went out to have a chat with the lil fella. I get out to his car and asked him why he was honking his horn disturbing my neighbors. He said, "I'm here to pick up Jen." I asked him if he was too darn lazy to walk up to the door and ring the bell. He looked at me like he didn't understand. I then informed him it was obvious he didn't respect my daughter much because he was too lazy to walk up to the door and told him to put his car in reverse and leave quietly. Apparently his hearing wasn't any better than his manners because he replied with, "huh?" I repeated myself and he tells me how he has a date with Jen. I told him I just canceled their date. He calls me an "a**hole" and I show him my badge and tell him to quietly leave my driveway. He never asked her out again.
