I’m troubled why Grandpa and Grandma were associating with a known communist in Hawaii. This could not have been an accidental meeting. And why did Grandpa and Grandma leave young BO from age 9 or 10 in the care of a complete stranger? These are not the actions of normal grandparents. Something was afoot by those people.
