The crowd at the airport rushed forward. The passengers had been waiting for a couple of hours for an airport worker to open the door leading to the plane outside. No one was in a good mood. An old man got stuck in the middle of the rush, He fell down and his head hit the hard floor. B1ood came out of his head. He appeared to be unconscious. Everyone rushed past him, except for Dana. She called for help.

 A minute later, a young airport worker showed up. Hardly looking at the old man, she told Dana to get on her plane. She said the old man would be okay, and walked away.

 Dana cried for help. Another airport worker appeared. He told Dana to get on the plane. Dana said that she was not moving until an ambulance(救护车) arrived. The worker said her plane would leave without her. Dana said that she didn't care.

 An ambulance with a doctor and a nurse finally arrived. They put him into the ambulance and drove off.

On her way out to the plane, which was still refueling(加油), Dana saw the worker who didn't care about the old man at the very beginning. The worker said, “You're lucky the plane didn't leave without you.”

 “The plane?” Dana asked.“Who cares about the plane? How could you be so cold? That was an old man; he could have been your grandfather! How would you like it if everyone just stepped over your grandfather and went on their way?”
