Both thinks they are right

Ratan thinks Diya is irresponsible(seriously?), doesn't knows how to cook, always creates mess(seriously?).

Both thinks they are forcefully tied with each other, both believes that they are right what they are thinking. So it is actually hard to convince someone if they firmly believe their belief.

PS. What I love about Ratan is, he was jerk, still jerk, will always be jerk.
