What’s normal in one marriage can be unusual in another. Did the wife’s mother polish her father’s shoes? Did the mil polish fil’s shoes?
Does wife enjoy polishing shoes? Does husband not care about polished shoes and wife really does?
Does husband come home 1/2 hour before shabbos and jump into the shower and doesn’t have time to polish shoes?
Does husband feel a need to be pampered a little? Does he pamper his wife and expect this favor in return?
