Wow im amazed by nowadays children. They know they might be controlled hence they write in a language other than their parents language. Cool idea lol.
About your duty on this matter, i've no doubt that talking to your aunt is the best way. The online activities of a 13 year old should be monitored anyway so you shouldn't feel guilty. Your aunt should have done it before and when she saw that they write in english she should have asked her daughter to explaine her the reason(but then they say that we are practising english).
You should thank your 6th sense and tell your aunt everything you know. Good luck I wish I had a cousin who cared about me like you care about her. What type of cousin is she nesbat?
Your aunt is an adult, the 18 is also an adult. Your 13 year old cousin is a CHILD and no matter what, that factor is the primary issue. She needs protecting, we all know what it is like to be a teenager and how at that age we can get life (and people so so wrong!
Sit down with both your aunt and cousin and talk it through, I know that is hard but you will never forgive yourself if anything happens and you have remained quiet. You maybe the bad guy for a while in the eyes of your cousin, but you know what needs to be done! Facebook is so so dangerous, we had a teenage girl murdered here when she went to meet someone she met online.
(it is also a beacon that attracts and safe haven for paedophiles!) ps that will teach you for reading other peoples emails, have you heard the english saying "curiosity killed the cat" ( she is very lucky you did and you love her enough to look out for her!) good luck mate! TRULUV SAYS - LITTLE PPL STAY SAFE ONLINE!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
