Wow sweetie that was not a pleasant thing to witness, nor very becoming behaviour for a woman of your grandmothers age!
But do you know what it was that originally made them fall out.....sometimes old "wounds" never heal, and it sounds to me like your G.mother has kept that grudge inside for a long time...now its out she may feel better about herself.....its just a thought.......I am not condoning what she did (it wasn't) ....maybe there was a reason (in her mind), as she appears to have been very very upset setting eyes on the person.........
Give it some thought............
