The Megillah says about Mordechai (10:3):
דורש טוב לעמו ודובר שלום לכל זרעו
He inquires about the good (welfare) of his people and says 'Hello' to his children.
Maybe I'm old-fashioned. I would think that a father should first be concerned about the welfare of his own children before the welfare of his fellowmen. And, I would also think that he should give his children a much bigger greeting and a huge hug and have a longer conversation when he sees his children. Much more than just a passing "Hello".
Did Mordechai's promotion as vice minister make him so pompous that he forgot his priorities?
