I made the mistake of having a group conversation with both my sisters that day. My sister who still has a high schooler's experience is a little different from mine, but my oldest sister, who was part of the same conversation, had one kid who was definitely underchallenged in school in spite of a pretty spectacular gifted program, and another who just missed the cut off who was the typical great student type. So until it came to education, she's been my go to for advice up until this point. She feels early entrance would have been wrong for my nephew because he was "immature" as evidenced by frequent discipline issues centered around him goofing off. We have a genuine difference of opinion where I think my nephew would have had less behavior issues if he had been appropriately challenged. My perspective is different because of my personal childhood experience. It's do sad how the whole thing makes regular conversations about our kids growing up get twisted around sometimes.
