My wife and I both work from home. Why won't she shut up?

When I'm working, I'm in a train of thought and trying to either complete a design review, convey data to a client or record documentation in the client files, working with sales production or logistics, plus having conference meetings with my direct reports or my management team. I have deadlines to meet, reports to get out and slide decks to build.

She has her own office in a spare bedroom, but I work in my home's front living space, which is between the kitchen and master bedroom. She'll walks out of her office, having already started talking to the cats, the dogs, or she'll be on the phone or using Amazon Echo with her mother, her sister, her friends, etc.., then walk into the kitchen and start talking to me when she can't see me and then walk into the room I'm in already in the middle of a sentence talking to me, casually walking through the room to the bedroom and expecting me to be listening to her before she ever entered the room.

How do I tell her to shut the frick up? It's incessant, annoying, interrupts my work and more importantly, the few minutes I have to spare to jump onto TD. If I say I'm in the middle of something and can't talk, she gets pissy then uses it as an excuse to be in a bad mood. I don't get it. I don't go into her work environment all talkative and chatty. If I need to ask her something I first send a text asking if she is busy and ask if can I come to her office to discuss something.

Why do women feel this compulsive need to constantly talk, and more importantly, why do they think we need to be constantly tuned in like a shortwave radio to their specific channel frequency?
