Secondly he disrespected his lineage and this was direct insult to his parents and forefathers which TN was not able to tolerate .Means all people are not the same. If there is Dadi and Shuklain ,then there are also his parents and Madhav .
Thirdly ,to show his rebellious nature he ate egg. What does he want to prove ? Whether this act of his does not break the heart of his parents ?
Point is what Dadi and Shuklain did with Mazumdars ,whether Abeer is doing the same with his parents ,in spite of no fault of theirs ? Whats your take on it ?
