I was taking your rhetorical question to be (not so much personally directed as - a legitimate one to ask the politically dispossessed?) "So why did You leave ?? Ummm maybe you were talkin about that cottage-Marxist with the Porsche.. a preachin about his guilt, for not ever takin a Kulak to lunch - at his own lean-to?
So back to the Real question then: crapped drawers, I'd guess. Natch there weren't actual "political discussions"; few adults will give the respect due young folks in such non-discussions - like say:
The history instructor in Fast Times at Ridgemont High, who has the moxie to overlook the Bogus, Dude! patois of his marginally-failing student. The kid demonstrates enough of a grasp of the material: he passes him. Nice.
Anyway, I never saw her in a group of adults - where custom would have forced her to be less Certain in her pronouncements (?) but she was housebroken so.. Now someone actually suggesting something Good & True in MARX! (whom I doubt she ever even skimmed, like legions of the Faithful) ... t'woulda been Fun fer me, anyway.
She were an ~OK 'gramma' in other ways, but a Master Teacher about how to really fuck up your head. RIP.
BTW Bill: she had been married -one of about 4?- to a descendant of the Seward who 'bought'/ arranged purchase of Alaska from the Russkies! [cackle] So she went by last-name Seward.
Small 'world'.
