Sandwich boy

So yesterday I took the boys to the pool and there was this little boy there who was super aggressive and downright mean. So at one point he came after parker and scratched up his back pretty good. After that Parker would not go near him and he also vowed to not let the little boy come near cooper. On the way home he said to me " someone needs to clip that little boys fingernails. I mean mom they were so sharp he could probably cut up his own sandwiches with them"
