Syag, because knowing a lot of Torah or being iluyish doesn’t equate to being a talmid chacham. Anyone can be a rosh yeshiva too. That doesn’t automatically make you chashuv. Some people just want to be rebbish and caught up in the hock with their elite chevrah. That’s their simchas hachaim apparently..
Really, the best thing to do in the beis avel is to shut your mouth unless you pick up a que that the avel wants to hear from you.
