Cyber predators.

If my friend told me that he or she were planning to or going to meet up with somebody they have only met at an online chat or something similar online, I would talk to them privately about the dangerous that could be caused by doing something like this and if that wouldn’t work I would slap them back into their senses after that if they still decide to do it I would just say goodbye and hope to see them soon and if something happens to them and they go missing then I guess I would tell the whole truth about what happened that’s all I would do honestly.
