It is easy to think you can speak freely when outside in the open air.......however.....while showing a rural property, my buyers were excitedly talking about how much they might want to offer. They asked me my opinion..
I took them around the back of the barn, pointed with my index finger at a painted sign, and said nothing more.
You could hear a pin drop after that. We left immediately, went back to my office and closed the door tightly to resume our discussion!
Anybody remember the book by George Orwell, "1984?" We live in a world of cameras.
