Sexist crap? That's traditional house-wife stuff over there (and anywhere with a long-standing bathing culture.) Being a good home maker is a full-time job, as in, people literally pay thousands of dollars for the stuff a good housewife (or more rarely, husband) does. From maids to daycare. As for the bath, it's more a sign of the effort and love shown for one's partner. The point is it starts with, "I don't need to do X anymore..."
Also, what good neighbor she is.
