The other Side

As you are studying in a Cafe you hear the News get turned up and see that the North Tower of the World Trade Center is on fire. As you watch learn that a plane hit the Tower, and you feel great sorrow for the people on the plane and in the building.
After seeing the news, you couldn't focus on studying and continued to watch the news. You end up seeing a second plane the South Tower and start freaking out.
You start to wonder why this is happening and what you should do?
