How does Purim - in which we dress up, wear masks, play Purim games, - differ from Pesach in which there are no costumes and no masks and no games? It's that Purim was all about dressing up, about covering. Esther doesn't tell (that's she's Jewish); she dresses as a Persian lady. And also when her heart was grieving she wore lovely royal garments and beautified herself in order to find favor in the king's eyes, and the fate of her nation depended in the perfection of her make-up and the comeliness of her painted eye shadow. And in contradistinction to her was Mordechai who was covered in sack and ashes as he prayed. She was before a king; he was before the King of Kings.
And now to the feasts? From the beginning until the end - feasts. Here is the origin of the games. And so many secrets and sly diplomacy. Bigtan and Terash, Achashverosh and Haman, Mordechai and Esther, Esther and Achashverosh. Secrets and conspiracies. Not so with Pesach. There everything is revealed. From Moshe's being revealed as a Hebrew until G-d's revealing to Moshe at the burning bush. And the very public Exodus. And from the beginning until the end, all is revealed and known and everything is deeply serious. Without games and feasts. There is no redemption in costumes. The redemption is visible.

But Pesach is a matter of redemption, and redemption has laws and doesn't have chances, it has necessity and doesn't have successes, hence it has rules, and even drinking rules. Because there is law to redemption.
How does Purim in which we were commanded to give gifts of Mishloach Manot, differ from Pesach in which we were not commanded thus? Because
It is what
