Lets not forget Salman's step mother and sister-in-law are item girls. They are only getting respect because they married into big families.

A natural expression for any issue is normal fine accepted, but on this occasion it was vindictive and she was enjoying it. Initially I was very impressed with Tanisha, but as days went by her nasty side could not hide any more, I expected a better conduct from her specially when in her snobbish ways once said (what sort of people are in the house) (don't know exact words) she should hold much dignity which is expected from her background.
Regarding Item girls I can say many of the girls are talented dancers where many heroines cannot match and should not be painted in the same brush, every person has different responsibilities and backgrounds and what you expect from Tanisha is not this, that's all
