You don't have to pick the wallet up. If you saw it and just left it there, there's no trouble you could get into. It would have been better to pick it up and turn it in to someone responsible, but if you didn't, you can't get into trouble.
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.
