Anticipation: Giving up my backpack

I will soon start to give up one integral aspect of my life.  Tomorrow I will start a full week without using my backpack.  I will need to carry everything I take to school in my hands.  Hopefully I don't have to take a lot of stuff to school this week.  I am also afraid that if I set my books down, someone will mistake them for their own.  I believe it will be interesting to never have to look for my backpack.  I have become so accustomed to picking up my backpack before I go to class.
