Disgusting.....
I feel for her and her parents, in what seems to be a hopeless situation. How can you reprimand 6 y.o's? They had to learn this behavior at home.
I hope at least they get a 7-8 figure settlement, and criminal charges for the teacher who allowed that to take place in their class. Again, even disgusting is a mild way to put it. I don't know how I would respond. It wouldn't be pretty.
