i feel that it is important to raise the questions and answers while kid is in highschool (12th grade), for even if kid doesn’t have questions in highschool, later on may have questions and they think since they never heard the answers, there are no answers. this way, they can inoculate those kids before they even have the questions to know that there are answers. and for those kids who really do have questions, they can get the answers that they need.
kind of like the “shaeno yodea lishol” – you ask the questions for him. and for the “wise son”, you answer his questions.
