my goodness i never thought a rav’s speach could be so boring. In the shul i go to, he always has something interesting to say.
Although i do agree with you that whether or not youre interested it is a chutzpa to learn something else. When said what goes on , it reminded me of kids in class while the teacher teaches sometimes…do other homework, pass notes etc. But it’s very different here because they are all adults, and should act with derech eretz. (true children in school should also but thats another story)
