Do what you want. Forget what your parents think, they don't control you. It's your body.
Its a fallacy that piercings are temporary they are there for life if you wear your stud all the time. I personally think you are too young for all these piercings, my daughter is 14 and has 2 ear lobe piercings but won't have any more until she is older, thats if she wants any more. Too much on someone so young looks trashy, don't over do it.
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.
