The second time you call test you're creating a new local variable called func and defining a new window. Change that closes over that new variable. The changes you made to the original func by calling the original window.
Change are not relevant in the second call.
You are trying to refer to a local variable in a function with the syntax func.varname. That won't work, that's not the way local variables work.
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.
