It has something to do with how she was raised . KJ never stopped or reprimanded her when she was wrong or rude to others . She doesn’t listen to anyone including Usha Maushi and Virat has lost his voice after his recent mistake to correct her . His guilt doesn’t allow him to tell her anything.3. No, it is very difficult. Much as I love Sai Joshi’s pure kind soul & righeousness & coursge & honesty, she wld not make a good spouse (or for that matter, colleague or teammate). No consultative approach, never takes advice even from known well-wishers, wants to do everything her way, is rude when crossed, & disregards others wishes. Though well meaning she consistently undermines & undervalues others. I would not want to work in her team in the hospital or be her roommate either.
