Who is responsible?

Well, the write up was (and is) meant to be my free expression of thoughts as an individual and as a teacher; it is not meant to corner any one.
After watching the movie I felt the accusations laid against teachers and the management was unpalatable to me.
In my write-up I have only narrated my situation as a teacher and have not touched upon the management side which can be very sticky; because they can present their own set of problems adding on to that of the teacher.
And yes, these things need to taken on a case to case basis, for there is no general solution to the matter.
In this particular case of the movie, I felt a lot of problems could be avoided by the proactive interest of the parent instead of just 'passing on the buck' to the teachers.
However, I still feel very strongly that parents do have more time with their wards than any individual teacher.
A teacher can teach a child in a particular term/year or maximum in a particular level like middle school or high school etc. Moreover in today's scenario we do not have 'gurukula' type of systems where a student approaches a teacher and remains in tutelage for atleast the next decade.
Anywise I do not want to hurt the feelings of a parent, for parents who are extremely cooperative to teachers and understanding do exist but are very hard to come by.
