Someone DM's you who says they go to your school wants to meet up with you to give you an extra fidget spinner or an iphone that they don't use anymore.
Do you go ahead meet up with them? After all, they go to your school.
NO!!!!
They could be an adult pretending to be a child, it COULD be someone from your school who may not actually be a freind of yours who may want to set you up to get rolled on, it could be ANY dangerous situation that you may not expect.
