I didn't know it was Grandparents' Day and I'm a grandparent and great grandparent. I always thought it was just before Thanksgiving because that was when the school some of my grandkids went to used to invite grandparents for a breakfast.. Was nice as the older kids served us, coffee, tea, orange juice, some scones, coffee cake, and donuts and we enjoyed them while the kids put on little skits for us.
