When I got home, I picked up the washbasin and washed my wife's feet. Why is he so moved?

Of course she was moved by your doting on her! I guess you are getting married soon! Feelings must be very good. Your actions may make her feel your deep love and happiness will flood into her heart. In fact, women are often not demanding. Maybe you did something for her that moved her, but she will love you all her life. Your wife is a person with temperament, so cherish it!
