Rav Mordechai Chaim of Slonim zy”a (Sefer M’Zekeinim Esbonen) relates that a Rov once was in the bais medrash of Rav Menachem Mendel of Rimanov for davening on Rosh Chodesh. Rav Hersh, who was known for his extremely enthusiastic davening, was also praying there that day. He would often become so passionate while he prayed that he would grab people and shake them as he paced from corner to corner. That day, he grabbed the visiting Rov and shook him up and down, even knocking him to the ground and tearing his long coat before walking away.
The Rov first thought that he might be a great Rov who davens with much enthusiasm, so he should not get mad at him. After davening, when Rav Menachem Mendel held a tish in honor of Rosh Chodesh, he saw that Rav Hersh setting up the food and realized that he was the attendant. He then told Rav Mendel what happened and asked, “Why are you keeping a ‘shor hamazik’ (an ox that does damage, i.e., a wild, unruly person who harms others) in your home?”
When Rav Mendel heard these words, he put his head down on his hands for a long time. He then looked at the Rov and said, “How can I be upset at him? If they aren’t upset at him in Shomayim, how could I be upset at him?”
