Argument goes both ways.
Anandi does wear multiple hats
Alcholism - here involves an underaged kid procuring it by illegal means - and it is not just about alcohol it is about exhibiting deviant behaviour under stress.
Tomorrow under stress she might take to some other habit too
As a principal it is her duty to see that she gets punishment for breaking rules and ensure that her mother knows what her kid is upto.
As a social worker if the mother requests her for her help she can help
As for erring family members - how to handle them - trying to see the error of their ways and help them mend their ways is the responsibility of the family primarily and if the family fails in doing so either the law enforcement authorities or social service agenecies should take it up.
In fact making their erring family members correct their ways is the responsibility that the family has towards the society.
So helping her mend her ways is Nidhi's mother's responsibility and she is free to ask Anandi's help.
Strange to see people who equated turning up late to school or not doing home work to being caught consuming alcohol in school premises changing their tunes too.
Anandi realised that the kid has problems at home so is that a reason to deny admission to a kid in school?
Strange to see people saying that a person who indulges in illegal activities like buying booze should be allowed to get away with a warning.If that kid is not made aware of how bad the consequences will be through demonstration how will they know?
Actually Anandi should have called the police straight away because she was caught with alcohol which is a legal offence at her age.
