I am so angry at Gopi

Exactly a middle ground, not too naive and not too worldly. Too worldly is that person who thinks she knows too much and as a result risks the happiness of the family without considering the consequences, whilst Gopi in her naivety exists to make others lives easier, and what's the use of that, I thought slaves were abolished.

You can say for example Kinjal is too worldly, damn the consequences with her actions. Rashi knows her limits and plays the game better, she knows the middle ground.

Just to be clear I've not suddenly decided to be a Rashi fan, however, to give some examples today, Kokila told her to go in the Kitchen use the Kerosene cooker blah blah blah, she went and started doing it, but when her husband came to say i wanted breakfast but i can see your hands are full, i will get it from outside, her words were exactly that yes go and do that don't trouble me. Also in the diwali maha episode she and Urmila sabotaged Kokila's plans for the day by switching the gheer with oil, how long did Kokila put pressure on her, really long but she never cracked, Urmila came to save her but after ages, meanwhile others by then would have confessed. Several other times, hiding under the table to answer the phone from Umang to find out pregnancy of Kinjal, whilst Gopi picked a call from Umang, she listened and in her naivety assumed it was Elesh (it didn't cross her mind to ask whose speaking), so a middle ground is needed, and of the two girls Rashi will always delegate what she can't manage herself and I think she has the balance of innocence and worldliness.
