the whole story and question is this: the three year old boy was waiting on the top of a little slide at the school for the little girl in front of him. He got frustrated and pushed the little girl who then fell and dislocated her elbow. my question is: should my friend be worried about getting sued? would it fall under the parents responsibility or because the child was under someones elses supervision would that supervising party be responsible, or would this fall under silly kids and they shouldn't worry about a lawsuit?
