Sometimes for the daily soap purpose these characters are little bit over dramatized but they are not totally wrong in their thoughts. Taiji was up to mild taunting till she started doubting. Now she is somewhere sure that something is wrong with naina and she is right we all know.
Sometimes we forget that sameer was really a spoilt brat. He was rude, angry and he even bet on girls emotions. Not everyone has seen his humane side like naina mundit n nanu. For an outsider his image is bad. Personally o feel even Rakesh hate him not out of some personal selfishness but he truly feels sameer is a bad boy. And he has enough evidence to prove his point. Dadi is same. She has slightly personal disliking for sameer as he is vishakhas kid but if sameer was like Rohan all good and obedient she wouldn't hv done things to torture him.
Very nice post!
