Keke Said, 'You are not My Friend'

We warned Keke to be away from her little friend. “打人的孩子不是好孩子。” I told her. And she nodded her head. I saw it two times that, from no reason, that little kid went forward to hit Keke’s face.  Keke doesnot have much attachment for that kid.  She usually plays with other kids now. She also said to that kid in front, “你不是我的friend.”
