question:
I was super hungry between classes.  I had skipped lunch again.  I know that was a bad idea, but I used my lunch period to study.  Now my stomach was grumbling.  I walked down the hall to the vending machine near the office.  I knew there had to be something there that would hold me off till I got home.  I smiled when I saw my favorite snack.  I reached down into my pocket and pulled out a dollar bill.  The machine wouldn't take my dollar though!  A girl passing by traded my dollar for a crisper one.  I tried again.  This time I was successful and the sugary goodness would be all mine!  I pressed the number on the keypad that corresponded with the snack I wanted.  It slowly edged toward me and dropped down.  I reached down to pick up my food.  I thought I deserved it now. 
Question: Why did they purchase something?

They were hungry
