Just go onto your chat log from a computer or on your phone and where it says "chat settings" just say "turn off chat for all friends" sign out and back in and it should take effect. Obviously I have done this before and people have told me it still says I'm online even days after turning it off. Facebook is full of glitches.
Delete the chat app as well and make sure it's signed out.
If Facebook shows it then nothing you can do to change it.
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.
