Reply To: Is “sir” a British thing

I know someone whose wife sent a check to some tzedaka organization. She received a computerized acknowledgment addressed to הרב. She said that she was insulted that they didn’t write הרב הגאון. On the other hand, some say that a gaon is someone who never heard of Rashi or Tosafot. There is also ה”ה (ha’adon hanichbad) Some say that there is also ה”ה”ה”ה
(הבל הבלים הכל הבל).
