Security and Nosy Neighbors

I saw a notice from a popular home security service company. The company wanted customers to know about a scam that some folks are using. They knock on doors, and claim to be from the security service company. When they are invited in, they check out the homes and examine the alarm systems. When homeowners, who are fooled by these folks, give out confidential info about their security systems to the scammers, the security of the home is compromised. The scammers can later shut off security systems and break into homes.
My first thought on hearing about this was, "Are you kidding me? Now the security company has to alert customers about the security of the security system?"
When I was growing up in our old neighborhood, the number of people living in your house and your neighbors were your best security system. We used to have some neighbors who could tell us who came by our house, the time they came by, and what they wanted. Day or night, there was always some neighbor up and watching out. Sometimes we children were annoyed by these neighbors; we thought they were nosy, especially when they told our parents on us for something they saw us do.
I just had a flashback! LOL!
Take care,
