I can only try-
When we were learning the Megilla in 4th grade our Rebbe pointed out one of the places (?????? ????????? ??????? ???????) to show that even though His name is not mentioned anywhere in the Megilla, never the less He was still “lurking” in the background.
Four years later a cousin of mine who was a very talented Baal Korei was laining the Megilla for the first time. (He was also a recent Bar Mitzvah at the time but regrettably he didn’t continue his talent as he got older.) I teased him that if he really knows the whole Megilla inside out, backwards and forwards he should show me where the name of Hashem is hidden. To my surprise he showed me three additional places as well.
