Exercise 5 number - 2

2)  A factory employee dreamed one nigth that  his boss  would be killed in train accident  the following day. Frightened, he called his boss  and told her not to catch  the train. His boss caught a different train, and  avoided the accident. When she arrived at work she thanked the man and then fired him. why ? 

I think that she  was very frightened and believed that maybe was real and decided catch other train when see that to pass nothing she was angry maybe  and decided fired him.  Maybe, she thinks could be  a joke.
