That just goes to show her true nature. The apple obviously hasn't fallen far from the tree...Both her mother and grandmother and herself for that matter would play these kinds of games so they naturally just assume everyone is like that...
She did the exact same thing to Adhiraj when she accused him (offhandedly) about just trying to appear gracious and a nice guy in front of her for buying those kids their biscuits...
I truly hope that Adhiraj is able to change her way of thinking and soon...
