No Vinegar on Rosh Hashanah
ABSOLUTE POSITIVISM
Some people love having vinegar in their salad. We can suggest that despite the Maalos of bitter things, on Rosh Hashanah we avoid even that. We are extreme in our positivism. An Adam Gadol pointed out the Gemara that says: עָהֶם הַכָּתוּב the Torah goes out of its way not to write בְּהֵמָה טְמֵאָה (an impure animal), just: אֲשֶׁר אֵינֶנָּה טְהֹרָה (an animal that is not pure). “Don't say so-and-so is not frum. He's not frum yet!” Those who watch to make sure that every move they make should have a positivism, have astounding successes.
When R' Gershon Liebman Zatzal would meet me, he would smile and say: "Of course you learn plenty of Mussar". Such sweet Eidele Hanhaga (not wanting to criticize, or giving Eitzos) “Of course you learn Mussar!"
I saw the same Hanhaga by R' Chaim Tzvi Fogel Zatzal, a Slabodka Talmid of R' Meir Chodosh Zatzal. I was told by some Slabodka Rosh Yeshivos it was like the worst sin to even hinta: גְנַאי negativity about any human!! B'shita!
Avoid anything that even smells of negativism, and expect big Yeshuos!
