You should ask them. If it's an emergency, then ask them. If you were just curious, then you could wait for them to tell you, or you could still ask.
If this case is an emergency, then just ask casually. Don't freak out, screaming, or anything. Just bring it up in a conversation.
Then, if everything is calm and still, it should work out fine. If he/she starts yelling at you for asking, then you married the wrong person! (Just kidding!).
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.
