Hi all I'am excited to be here and I was just wondering after you turn your lights out for the night. Do you answer the door if someone Knocks?? I had an interesting story I was in Las Vegas visiting and was parked on the street.I knew I was legally parked at 4 AM a police officer knocked on my door. I did not answer it and he went away. At 8 am he came back and knocked again I said through the door may I help you ? He said would you open the door, I said would you please put your face and badge up to the window? He did it then I opened the door and introduced myself. I said is there something wrong? He said no he was just checking. He did not ask if I was here earlier and I didn't say anything either. I said I am an older women and traveling solo so I am careful about opening the door. Then came the most important question what is this and what year????? Oh he said, I just smiled and he said ok bye and left. Unless I know who it is I do not open my door after dark.
