GH: >>escape the real world >> filling in as surrogate teachers
I feel opposite on both issues:
– an opportunity to connect to fellow Jews and hear different opinions
– an opportunity to fulfill mitzva “ve shinantem levaneha” on your own instead of using some randoms as substitute parents. While the process is not without challenges and negative parts, we enjoy discussing interesting things with kids instead of reacting to what schools do to them. YMMV.
Encouragement for grandparents here: says somewhere that someone who teaches a grandchild gets olam haboh. Explanation – parent can teach a kid merely by example. Grandparent can not, the kid can not relate to his example that is too far removed. So, a grandparent is force to teach in a way that generalizes from his generation to the kid’s, and that merits olam haboh.
