Answer:
Dear Diary,
Today, once again I find myself struggling to keep moving forward in this horrendous lifestyle I'm having. I'm in charge of collecting all of the belongings that was once in possession of a Jew. All for the pleasure of the Nazis. I now find myself keeping any money or paper I can find to use as bath tissue for me and my friends. There will never be any words that I can use to describe how horrendous this place and this life is. The feeling of waking up and having someone dead beside you is unthinkable. We all work so hard to just survive one more hour. What will happen in just a few hours is a big mystery for all of us still working. You cannot rely on someone. just when you think you find someone to trust they end up leaving. My only hope is to be able to get food and live through one more day to write in this diary again.
this only works if you are talking about the concentration camps the Jews were sent to by the Nazis.
