A few years back when I was in middleschool, there were some asshole high schoolers that lived in my neighborhood. Everyone hated them which probably fueled some of their antics towards kids. Anyways, me and my friend were walking around the neighborhood, saw them hiding in the woods and shit and egging and powder bombing little kids as they walked by. we went back to my friends house and got his older sister and her guy friends, grabbed paintball guns and chased them through the woods haha. It was great. I think that was the last time they ever caused problems on Halloween.
