Joseph, as both a parent and a Rebbe, I must agree with TLIK. I have ample opportunities to teach my children about Kibbud Eim, and I never say anything about Kibbud Av. My wife does vice versa. With my Talmidim, I model Kavod Harav whenever I have the opportunity (involving the Menahel or other Rebbeim), and I take advantage of whatever opportunities I get when I observe my Talmidim interacting with other Rebbeim in a way which doesn’t fulfill the Halacha, but I do not ask for it for myself. Kavod HaAdam is the easiest; I demand it on behalf of each child or Talmid…
No matter how correct, there is no effective way to teach, “you must respect me.”
Don’t worry; your teachable moment will come. The same student who disrespects his Rebbe will soon disrespect the Menahel. The same child who disrespects his father will soon disrespect his mother.
