Women who can ...

In the movie, 'Alex and Emma', Emma says to Alex.

"Like when its time for the first laundry. I know, I know. In great romantic novels there is no laundry or there's people like Ylva or Elsa to do it. Maybe that's why I like them. They can wash their own clothes."

Why do long buried things surface to the conscious mind when what it (the mind) should be doing is deliberating on the assignment?

Weirder things happen. Emma and her words popping up out of the blue is still close to normal.
