We went to a gathering on Shabbos together in someone’s apartment. Rav Avrohom stood in the back with me. Suddenly, they saw he was standing in the back and grabbed him and put him in the front at the table.
When I traveled across Eretz Yisroel with Rav Avrohom for his Bein Hazmanim shiurim, he would personally review my notes to see that they were accurate.
A rabbi from one of my yeshiva’s asked if I could bring back some Torah from Rav Avrohom. After Shabbos he wrote down the drasha he gave on Shabbos for this rabbi.
