Are you asking on what to tell them? If so I’d tell them to talk to somebody who they trust who has power to do something because I know (as a person who has been bullied before) our voices aren’t ever going to be heard so if they trust a teacher, a parent, a grandparent, (ect) tell them to tell everything that has been going on have them do something, by speaking with the teacher or principle to make sure that this kid doesn’t follow them to demand money. Or have them they aren’t going to give them any money and if something more happens than speak to someone, also speaking to the guidance counselor helps!
