In my house everyone (6 people) share one bathroom. Consider yourself lucky. As for the room, see if you can talk to your parents about getting separate rooms if you have an extra one.
Try to be persuasive and give good and valid points about why you should have separate rooms. Good luck.
Talk to your parents about it, maybe they can arrange it so you can sleep somewhere else.
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.
