Sorry for your situation. Unfortunatly it is a problem many people has experienced. You can always try to start putting the rubbish they don't clean in front of their room door.
:)Another option is starting to take pictures of it and tell them that you will start showing everyone how they are. The last and probably best option...start thinking of moving out and finding someone like you. Good Luck.
I had faced this situation with one of my rommies. I tried reverse psychology and started cleaning up his part of the room too. It took time but he realized that even he should do some cleaning and after about 3 months he started cleaning his mess on his own.
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.
