At midnight one middle-aged man was waiting at a train station to cross the
 country to back east to see his relative. As he stepped up into the train car
 he noticed that the car was almost empty except a young beautiful nun sitting
 by herself reading a bible. The man came and sat near by her hoping to get
 some companionship during the long ride.

 However, the nun was paying no attention to him. She just kept on reading
 bible without even looking up to him nor saying a word. Half an hour went by
 slowly and silence made the man more and more anxious to start a conversation.
 But he did not know how to start. The man then put his hand on the nun's lap.
 The nun blushed with a little bit of anger.

 She turned around and said:
 Nun: Dear sir, do you believe in god?
 Man: Yes, I do.
 Nun: Have you read the bible? You know it is wrong to put your hand on my lap.
      Perhaps you should go home and read line 23 on page 157.

 The man withdrew his hand and sat quietly till the train reached the east
 coast. Next day, people found out that he shot himself in his room while the
 bible lied open on page 157. Line 23 read: "Heaven is a little bit higher."
