pankudi and pooja episode discussion

pooja -her not going out in public is something very very natural ,i mean most of the people who are either fat or thin,generallt tend to avoid public ,their confidence becomes low ,its only when you grow up ,you tend to learn how to handle your self .raghav was only person who could make her forget all insecurities...pooja s most of actions were justified except the last step to kill pankhudi,did ul notice the both boys would try to peep into pankhudi neckline ,pankhudi would wear such tops where boys attention go over there ,,whether it was sujit or even raghav pooja also  noticed  it ,even when wen she was in pool with raghav ,pooja was constantly telling her about it but pankhudi dint bother or she was careless,i think as a sister she had to maintain her decency infront of her sisters boyfriend ,why was so ignorant about her sisters feelings?
