You walk in to the computer classroom. You sit down at your computer. You notice that the computer was left on. Someones online accounts, photographs and classwork is open. What is the right thing to do? What would you do? Why? Should you go into the other persons accounts?

The right thing to do is to log off the person's account.  I would log off the person's account because if that was me I wouldn't want anybody messing with my account.  No, you shouldn't go into the other person's account because you can mess something up that they worked really hard on.
