Dear Harry, The only reason your granddaughter is ‘tense’ is because of the lies you and your daughter-in-law were filling her full of. Your own selfishness, greed, and hate has flowed to your grandchildren. I hope you are “proud.” (sarc)
My guess is that they are tense the same way Goebbels kids were antsy in the bunker.
They did not really realize it, but they could feel the noose tightening. They were not guilty of anything but their genetics.
