I so completely agree with you!As of now, she is the fire extinguisher to Ani's fire. She has shown extreme calmness in all situations depite distress and behaved more maturely than a certain London-return-Barrister.
She is like earth... All accepting!
Ani is hyperactive... There are so many facets to him.... He needs someone to hold him in place... To be there for him and understand him. Mini is far from even giving a thought to what Ani wants... But Bondita has accepted him the way he is. She understood him and even shown interest in things her pati babu feels inclined towards... Unconsciously it makes her understand him better even than himself.
