Rav Henoch Leibowitz Gives Away His Yarmulke
Rather than rebuke a bachur for an inappropriate yarmulke, Rav Henoch Leibowitz hands him his own, and the bachur wears it proudly.
From the article
On another occasion, a bachur was wearing an inappropriate yarmulke. However, the rosh yeshiva didn’t want to give mussar to the talmid. Instead, he reached under his own hat, took off his yarmulke, and handed it to the bachur, saying, “Please take this–I want you to have it.” The bachur wore it proudly!
