Hi Rabbeinu, Still love your blog. I found this and thought of you. It's a maysa about Rav Baruch Ber from Rav Yehuda Gershuni, otherwise known as Yud'l Grodner, one of the greatest illuyim of the pre and post war generation. He had semicha from Rav Baruch Ber, among others. He was later a talmid of Rav Kook and eidem by Rav Eliezer Silver. This is from a sefer zikaron about him called Afikei Yehuda.

"בע"כ יענה אמן" - Bakehilla's Yaakov B. Friedman brings us the inspiring story of the Lubavitcher shliach in Grodno, Belarus

חס ושלום - I don't mean to say that he's a מלאך רע, it's a שם המושאל. He's a shtarke Litvak who has taken an interest in Grodno because of its history, and is especially interested in the Lubavitcher shliach there. He has written about Grodno before, and now, after the devastating fire there, writes about Grodno and the even greater difficulties faced by shliach Reb Yitzchok Kaufman. He cannot wrap his mind around the fact that a young man would come to Grodno to spend his days with old Jews who just use him out - and basically asks him that every chance he gets. Box.com link
