We had a home invasion. They cut the phone lines so that the alarm system wouldn't call the police. Part of their M.O. was that they'd watch a house from the woods in the back yard for activity. If they didn't see activity and noticed just one car, they assumed the owners were absent. Well, Big D was in Tokyo, so his car was at the Atlanta airport, and BJ and I went to bed early because it was just before exams, and I had worked my butt off getting my final projects, study guides, and exams ready for my students.
The burglar alarm went off when they broke down the back doors, it woke me up, I unsuccessfully tried to reset the alarm, and I attempted to call the police for help BUT THE PHONE LINE WAS BROKEN! We ran down the stairs, saw the back of the house broken down, ran to the car, ran back to the house to get the poodles, and drove to our neighbor's house across the street to get help. Unfortunely, the last flight from Tokyo had left, so Big D couldn't get home for two days. My brother drove from Newnan with his gun, and we sat by the broken down doors with guns all night long in case the burglars came back. We shot off a few rounds just for fun and to scare them in case they were waiting back in the woods to re-enter.
So, yeah, to make a long story short, I am very defensive about protecting my family and my property. And, yes, we now have backup systems so in case the phone lines are cut or either AT&T or the cell phone is out, the alarm system can still notify the police.
