Because you are in her kitchen (literally and figuratively). When women want your help they want it side by side it's social and working together- connection. Not to fix the problem or pick up the slack.
That's why when I renovated our kitchen I removed the entire wall an built a bar.
Now I can sit at the other side of the no fly zone and socialize and be connected without being an obstruction.
When W wants a pot, a pan, or a glass, I can get up an get it for her. I never do it without being asked first. Mindreading makes her mad.
