The reason is that elders never expect their younger ones (we can say the immediate generation) to reciprocate back at them and younger ones cannot bear the Monopoly of elders over their own opinions.
These results into non-acceptance of each other views and then the tussle exists between the two.
Of course old generation cannot bear opposition from youngsters as they consider that youngsters should obey him blindly whatever they say.
Now the demand of the current scenario is that we have to think over ourselves as a friend to our offspring by keeping aside our ego of being elder.
One has to give more time with to the children and recognise their needs.
It should not be that you are ordering something and the child has to follow that blindly.
