Lori, if that is your theory about it being someone you know to get you to secure your home, that's not the way to do it. Instead, it brings alarm that someone is trying to break in!! I don't know that many people would use that method to get you to secure your home. I think they would knock on your door, call you, text you, and say "Hey, Lori! Please be sure to secure your home!". NOT intentionally make it look like a break in to scare the bejeebies outta ya!!
I'm glad you have a pretty good security around your place. But next time, when your dogs bark, pay attention. They do that for a reason. Yes, sometimes it's only because they heard a cat or another dog, etc., but I wouldn't ignore it until I check it out.
Have you had any recent incidents since posting about it? I hope not!!
