If you love this 'close relative' you'll accept her with all her flaws, and that includes not wanting to have her picture taken. She's not going to magically change just because it's your wedding. Photographs aren't necessary to remember your wedding, honestly.
They're nice, but they're not necessary. If she's not in the photos it's not going to affect your memories, at all. Now you have to decide whether to accept her as she is, or create a furor by kicking her out of your wedding.
Your choice.
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.
