Remember the story of the fire in a movies theater. People were running all over each other to get out. In fact there was a man who took off and forget about his pregnant girlfriend. He did not think about her, until later after he had gotten out. She survive, in fact, he even ask her to marry him after that happened, and she said yes.
Have you every said good morning to a person, they acted as if you did not exist? How do you see yourself in life? Are you just living for you?
