A Pearl Necklace

A young woman was taking an afternoon nap on her birthday. After she woke up, she told her husband, "I just dreamed that you gave me a pearl necklace for my birthday. What do you think it means?" "You'll know tonight." he said. That evening, the man came home with a small package and gave it to his wife. Delighted, she opened it--only to find a book entitled: "The meaning of dreams".
