“Once a Rav brought another rav to meet with the Chofetz Chaim , and the Chofetz Chaim threw the second rav out. As the Chofetz Chaim was not known to act this way. The came back a second time and he threw them out again.
The came back a third time and before he could throw them out, The 2nd rav (The one who was thrown out) asked, Why do you throw me out.
The Chofetz Chaim asked him do you remember Lev Bronstein. The rav answered. YES I do. I had to throw him out of the yeshiva..
The Chofetz Chaim told him that Lev Bronstein was now Leon Trotsky head of the Bolshevik Revolution”
But that melamed didn’t trow the kid out because of bad behavior, he refused to learn with the kid because his mother was a poor widow who couldn’t pay for him.
