also be careful of those that usually use a female to knock at the door and say she needs gas money there is usually guys with her or waiting in the car. she comes in to see if it worth them joining her and then you have a home invasion going on. one knocked on our door at 2 in the morning smelling like a bar. my husband told her we had no money but he would see is we had any gas left outside by the time he got back to the door she was gone. i was so pissed at dh who opened the door and let in side it .he wouldn't listen to me at all. then when she was gone he believed me i told him someone was waiting for her. he better not do that ever again. i was a little scared then. we were just lucky plus we don't have anything here in this house to get. we sold and got rid of everything before coming here. him being so helpful all the time has gotten us in situations that could of got us killed. he needs to stop it. that is why we have policemen that are trained to deal with things like this.
