Save a child,  report suspicious activities.  If you see an adult with a dirty unkept child or the child looks like they have zero self esteem and the adult does not allow the child or teen to speak for themselves these are warning red flags. Mind you there could  easily reason why the kid is dirty maybe he was playing at the park. We don’t want to start accusing innocent people but you want to learn what stands out as abnormal. Use your discernment and discretion. If something doesn’t feel look right it probably isnt.
