Yes, last night's episode had an interesting twist. It showed that not all teachers are good and have the best interest of their students at heart. Many times, we are quick to blame to child, but we should listen to them fully (like Shivaye said). It also showed that you should not pressure your child study more than they are able to (like when Bobby wouldn't let Bablu go to bed because she wanted him to study more).
It was interesting that they brought back the topic of shak (jealousy) again. This time is was BD doing the shak-ing instead of Bobby, but they presented it differently. A husband and wife's relationship is strictly built on trust, and if you cannot trust each other, then the relationship gets strained. BD should not have followed Bobby like that, but he's human! Most of us would have done that too. It's not right though; you always need to be able to express yourself honestly to your spouse.
