I would say something to the kid and/or then to the parent. We have many kids in our neighborhood and I even have them. Kids are going to be kids- I know it is more annoying to people who do not have them, but they are kids. Usually if you say something to the child they will stop. I have gotten on to a few kids in my neighborhood. One will always walk out in front of my car when I am driving. So Finally I had a talk with him. He has been better about it. Then sometimes they would go in my yard when I am not at home. I told them all to stop and they did. I just would not want them getting hurt
