Hey ASHU, it's not easy to share your insecurities, especially with someone about whom your aren't sure yourself. And when the situation happens to be mired in such stark contrasts the situation becomes even more complicated. II would like others to see her as a confident, upright, hard working and a proud woman, by airing out how she feels she fears people might judge her as someone who is unsure about her own status in life and is trying to zabardasti be someone she is not...while that is not the case. You can in,y fit in when the people around you accept you for who you are, not when they make you feel an outsider.
RB doesn't really have to adjust, he is but a mere visitor at her home for a few hours. Yes he wants appa to like him but it's not priority number 1 for him.
RB in my opinion as many other men men has linear thinking, he deals with situations on an as is basis without seeing the entire picture. Women are more complicated in this respect - there are layers an slayers of thought processes.
