As a character sanchi is cheap.She can never keep anyone happy until she gets a jhatka an change her thought.Sanchi is fun loving,childish,full of life,is just bull crap.If someone adds this qualities with sanchi then people will think that to be childish,immature,full of life,fun loving is wrong.If you insult a person without any reason it can't be avoided as childishness.Sanchi will behave the same in her eighties also if she doesn't change.When I think about sanchi four incidents come to my mind...She took her molestation as a weapon to blackmail her family,she faked that she can't face the mirror...She was trying to impress jagya by wearing short dress...She insulted her bhai and bhabi in their sagai by showing how her to be bhabhi has trapped her bhai...She was allowing sunny to touch her thinking him as jagya...I am leaving the ganga incident just because sanchi dislikes ganga.The girls who can fake with her mother,brother,also the person she claims to love,I can't expect any good behaviour for others.She is not childish,she is plain cheapo.And she can never be happy with anyone.She has the power of destroying a person's life within a moment.She is among those kinds of girls for example a girl proposes a boy and the boy refuses,the very next moment she will get angry and will tear her dress and claim that the boy has tried to molest her just to take revenge.Sanchi can be easily put to that category.
