Why are women obsessed with decorative pillows?

My wife, as do all women I guess, has a thing for decorative but otherwise useless pillows on everything, which is why I found this cartoon humorous.....

And the decorative pillows have decorative beads, sequins, and other assorted decorations that if you dare touch the pillow, they fall off onto the floor and you get yelled at. on every couch and chair in our house sits at least one decorative pillow. Our bed has no less than 6. Literally the entire top third of our bed is covered with decorative pillows. It's not that I don't like how they look on everything I guess, it's just that having to be careful of pillows doesn't make sense.

And they have a very specific, rigid arrangement that is not to be tampered with or altered in any way. If she ever notices an out of place pillow, there's a long-suffering eye-roll directed toward me followed by an immediate remedy to the situation.

In my own defense, it's not easy memorizing the exact positions and orientation of like 25 decorative pillows around the house that I'm not allowed to lounge upon.
