My younger kid is a senior in high school and will be turning 18 soon and there’s no way in hell she’d ever consider behaving that way. I feel super lucky/blessed to have both kids turn out as well as they have.
My guess is the parents are wealthy and have spoiled her since birth and she feels entitled to whatever she wants and this lawsuit is little more than an expensive tantrum. Time for the parents to rewrite their will and omit a certain bitch from it. And they need to let her know about the change.
There was also domestic abuse allegations against the parents, with a teacher as a witness. There is no reason for the parents not to pay the last yr of her hs tuition.
