You can delete a friend from Facebook by going to their profile page. When you scroll down to the bottom of the page there is a link that says: "Remove from Friends" You can find out more information on removing friends on their help page but this will work if all want to do is delete them.
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.
