Since, Khushi is a street child that is why her language is said to be not so refined and having a rustic texture. It is true but that language we get to hear when we see street children talking in their own circle with other street children and not when they talk to people like Dr.Ashutosh or Dr. Nidhi. As far as, I have seen, street children are very hesitant in even talking to people of educated class, leave alone the language and tone in which Khushi is speaking. Whenever, I call girls similar to Khushi (social background) in Navratra for Kanya poojan, I have always found them very very hesitant and even if they open their mouth they speak in sweetest of tone. I have never found them loud mouth like Khushi. So, here I disagree with the justification of Khushi's tone and texture of language, while she is speaking with Ashu-Nidhi.
