The probability of reversing course during open discussions within households

Our parents never showed their difficulties either financial or physical in the presence of children by thinking that it would affect the minds of children in everything including education.
In those days the parents never discuss the house problems either financial or other, in front of the children as that might affect their education of them. Nowadays, parents are of the opinion that the children should know the difficulties of parents and so in front of them they discuss, fight argue etc., without minding that that would affect their education as well overall mindset. Nowadays, even, in many houses, many complicated discussions are openly discussed but useless things are discussed and shared with pure privacy. 

Similar to that the discussions questioning etc., about the student with a teacher or HM or Principal should be made in the absence of the student and also in the presence of other teachers.
