You are studying in the Bonaudi Library study rooms at Big Bend Community College and you've fallen asleep.  You don't hear the announcement that the library will be closing in 15 minutes.  You are so tired from studying.  The lights go out, it is dark and like most libraries, it is quiet.  

Suddenly your laptop starts to beep loudly. Startled, you wake up.  Your laptop has just died. You forgot to plug it in. The paper you were working on is gone, you didn't save it.  All that work, gone. You worked on that for a whole 15 minutes.  You'll have to start all over.
