That's definitely a toughie!!
Taking into account our Indian traditional upbringing(irrepesctive of whether the girl is born and brought up in abroad or not!!!), I feel --especially from the girls point of view she will not stoop so low to insult a person verbally in such a harsh manner(BTW I haven't seen any Saas-Bahu serials so far!!)..
