Well, that’s gratitude for you.
Nope , gratitude has nothingto do with it !
It's about FAMILY SURVIVAL !
and a racist, ignorant, lynch mob organized for any alledged social wrongs !
They are thankful for George and his actions , and that's all that anyone would expect !
However , so as to remain somewhat anonomous , the family isn't loudly exclaiming his generosity and consideration
its more than that !
And more importantly , it's between George and His God who already knows his heart !
I suspect they've already expressed their thanks to George - and I doubt that he blames them for trying to publicly distance themselves from this insanity.
