No, no one has called us. That's terrible!!
We do keep our phone ringer off. If we don't, we get non-stop scam/spam calls, so one day a few years ago this bright light turned on in my mind ---- why am I letting these criminals into my house? I don't have to, I can just shut them out! Off went the ringer and if it's a real person, they can leave a message. If the plumber is expected or some such, we can turn it back on for a few hours. It's wonderful the misbehavior and manipulation we avoid this way.
