I dont disagree that Avni needs help, but i do disagree that she's uncultured/illmannered/etc.
shes acting as any ADULT would in that situation, if someone called you a najaayaz child, spouted nonsense about your mother, tried to keep your father 'imprisoned' (which is the impression that ashish has been giving her for ages now), dont tell me you wouldnt get angry. dont tell me you wouldnt want to throw a rock at her. you WOULD, but because you knew the legal consequences, you'd probably try to hold yourself back. this child is being forced to react because no one is listening to her heart breaking. her mum's too busy wallowing in self pity, her father is too busy hiding in his mum's pallu. the only real stability she has is Ali, who, bechaara, tries to keep her sane. asha does tell her to stay respectful and be kind. and the episode where she saved neela just shows what a beautiful soul she has. she is also very quick to forgive, like she did Kiya. dont tell me these are traits of an ill-mannered, uncivilised child.
every 'well-mannered', 'kind' 'civilised' person has a limit, even as an adult. but because adults have years of experience in holding things in and an understanding of the law, we hold ourselves back. avni has not had the time to develop that particular skill yet and i dont think its right to call her uncivilised or ill-mannered for that. save those words for the 60year old who's threatening to KILL A CHILD to get her way.
