You are right. Gauhar should not mind but somehow I feel Gauhar gets upset when Tanisha say something about her. Why can't she shows the attitude of I DON'T GIVE A DAMN n laugh more sarcastically than Tanisha. Tanisha knows that this attitude of hers bothers Gauhar n she plays evil with it.
Simple reason... Gauhar is human too ! No one likes to be disliked ! Besides, if it was just Tanisha, Gauhar may have handled it... but because of the ice queen... the host unnecessarily targets Gauhar & Kushal week after week... And that probably is the worst. She has been in the house forever... neither she, nor Tanisha knows exactly how their images are being portrayed outside... Hiroo Aunty and Farida Aapa don't count... their bias comes from the fact that they are both close to ice queen's sister !
The real people of India can see who is right or wrong without any bias... This season has been such a let down, and its only because of the ice queen, the abuse king and the unfair host !
