Here's the truth. Now more than ever your son needs your support. If he looses you, he could never be happy.
The best way to show that he still has your love is to attend and try to be happy for him even if you may not be at first. Given time, you will see that he is truly grateful to know that you have his back. Besides, if you made that decision you would want the support of your family as well.
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.
