It was in the body language. I did not see Tanushree get mad or upset at all. She looked genuinely concerned and then she picked up and started dancing againg which encouraged Vineet to pick up again. I think Tanushree was very supportive there. I still remember in NB-3, there was this guy who got really mad at his wife for forgetting the moves and his body language was extremely insulting owards his wife. Wife's name, if I am not mistaken, was Ritu. We did not see Tanushree acting that way, did we?
That said; I did not get why Farah had to bring in the age factor in front of public. That was extremely rude.
