I think I'm on a list under the heading-Sucker.

Friendly people keep calling me. The address me by my first name and explain that what the have to sell is important. It's not.
I hang up often and generally after a bit they all go away. One is most persistent.
Michael called me and explained I had won a prize. What an idiot, I have never won a prize. I was about to be gifted with a security system...for free.
I told him to go away and never call again.
Today Steve called me and wanted to discuss my security system. I told him I have an Uzi and several of the newer arms all about the house, loaded and waiting for the arrival of an intruder. I'd plenty of target practice and figured I could kill without making too much of a mess.
Clearly he'd done some basic research on Kentucky, he probably even knew about the lady up the hill who killed a naked man when he broke into her kitchen.
I do hope I'm rid of these salesmen even though I'm probably the only unarmed person on the street.

I do have a security system. The damndogs could bamboozle most people. Nook gets overexcited and races around the house barking and missing a stranger by inches. Winnie can bark loudly too and she's a dab hand at imitating a pit bull when she's alarmed. All of witch just might distract a person until Mickey the stealth dog went in for the kill. He's the only one I suspect might bite.

Then there's me. If I hear an intruder I have recourse. I can call the police. John, a fervent believer in women's rights will generally sleep through any ruckus, but if it gets bad enough I can escape down the hidden staircase or open the window on the side of the house and scream, all sorts of non violent action.
And in the absolutely worst case I can pinch John until he has to get up and let me guide him to the safe route outside.
