My GF visited two of her oldest friends over the weekend. They were out to dinner when somehow the word "dinkleberry" came up. My GF's apple watch lit up and said "dinkleberry, a piece of poop stuck to a dogs butt". They howled with laughter. Her phone was in her purse and no one said the word Siri. So Siri is always listening or some nerds like to listen in on people while in their cubicles. I know Alexa listens to you all the time.
