How can one handle favouritism and partiality by ones parents. A friend of mine tells me that in their family, when her elder sister offends her, instead of her parents taking the right decision against her elder sister, knowing fully well that her elder sister is at fault, rather they blame her. In her own words she said " i felt like, i was an orphan, infact my mother once told me that i am very wicked from birth, that i would have killed her during my birth." i want to know what to advice her on what to do in such event or similiar event. I want to know your views.

Thanks a lot chaircover. Still expecting more comments.
