Must the CR attempt to address what already exists clearly in Shulchan Aruch? These halachos are detailed. However, there is a painful reality – many are simply not followed, and one may reasonably ask to know the norm.
Here’s my experience. Every yeshiva environment is different. I have observed some where speaking to a rebbe or rosh yeshiva in second person is the standard. I know it challenges the halacha to speak only in third person, but there may be redeeming value to this. Again, my personal experience. These rebbeim and roshei yeshiva are still connected to their talmidim decades later, and remain true to the derech of Torah that they were guided in long ago. There was no real distance between rebbe and talmid. Today, these talmidim do speak in 3rd person, but remain closely connected.
One of the traits of a good mechanech is the ability to maintain the kesher even years later. Sadly, not many succeed at this.
