Without actually seeing what you're trying to describe, it could be a myriad of things. An injury that is trying to heal or some sort of beetle infestation. I suggest taking a digital photo and sending it to your local Cooperative Extension office.
They can identify the problem usually just by looking at a photo and they wouldn't charge you for an online diagnosis.
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.
