OK. I know this has nothing to do with the subject, but I just gotta tell it.
The “red button” reminded me of an episode many years ago with my then new mother-in-law. We had taken her to a newly built mall for some shopping. The mall featured several of the “location” kiosks near the entrance, and we stopped to find the store we wanted. Mother-in-law askes “How do we tell where to start?”. I told her to press the red button. See did, and a flashing light showed up saying “You are here”. She jumps back, in shock. “Lordy”, she says. “How in the world does that thing know where I am?” Tried to explain it, but she would not go to the restroom all day. Said “I don’t want those people to know I’m in there.”
Became a family story repeated for decades.
