My youngest daughter has progressed by leaps and bounds from not being able to read independently a few months ago to being able churn through a few easy readers a day by herself (she just turned 6 last month). Included in books she enjoys is the My First Parsha Reader series. After telling us about Balak on Shabbos, she went back to Chukas and told us the story of Moshe hitting the rock and Moshe and Ahron getting punished. Suddenly she stopped in the middle and said, “Wait a minute - What did Aharon do wrong?!”
Two quick points: 1) How does formal education manage to destroy in short time this innate sense of interest, curiosity, and wonder that children are blessed with (and yes, it inevitably does)? 2) The Lubavitcher Rebbe in many sichos assumes that Rashi addresses himself to questions that even a 5 year old child would ask based on the idea of “ben chameish l’mikra”. Interestingly, Rashi does not address this issue.
