Yes Parvati need not have told her mother she doesnt need the gifts because there is no "bhavan" to keep them. Earlier also, Mena had brought gifts and laddoos, that time Parvati accepted it. So why now? Especially after her husband explained to her nicely. This was unnecessary...Parvati asking for bhavan even for her children makes her "human"...not Aadishakti/Prakriti.
I have been wanting to tell this for sometime now abt the shringar thing. Parvati expecting Mahadev to do her shringar especially after banishing him from entering Kailash was a little odd. If Mahadev himself had shown interest in doing Parvati's shringar out of immense love, then this shringar track would have gone to a whole different level. I feel that Cvs are showing Parvati very very human and abla nari...Not a strong Aadishakti. Just my opinion.
