I think they think the girl still might have feelings for da guy if she has somethin of his. Or he was really special to her and he wants to be the only special one. I dunno thats what I think of 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.
