Agree that they were harsh words, but Meera brought this on herself. I have zero respect for a girl who acts as a home-breaker... No matter how pure she claims her love is. Love is NOT chasing around a married man, staring at him, hugging him, and then claiming her love is pure. I don't think love makes you senseless and stupid. If she is breaking up a happy couple, she is the worst excuse for a woman in this world.
Krishna was right in saying what he did. Meera can't be excused from listening to harsh words just because she is a girl. Her actions brought this about, and she deserved hearing each and every word of the convo. There shoule be no pity for her.
