 Person1:       Hey Lydia , what are you reading ? 
 Person2:I ’ m looking at my horoscope for this month ! My outlook is very positive . It says that I should take a vacation to someplace exotic , and that I will have a passionate summer fling ! 
 Person1:        What are you talking about ? Let me see that ... What are horoscopes ? 
 Person2:It ’ s a prediction of your month , based on your zodiac sign . You have a different sign for the month and date you were born in . I was born on April 15th , so I ’ m an Aries . When were you born ? 
 Person1:        January 5th . 
 Person2:Let ’ s see . . . you ’ re a Capricorn . It says that you will be feeling stress at work , but you could see new , exciting developments in your love life . Looks like we ’ ll both have interesting summers ! 
 Person1:        That ’ s bogus . I don ’ t feel any stress at work , and my love life is practically nonexistent . This zodiac stuff is all a bunch of nonsense . 
 Person2:No , it ’ s not , your astrology sign can tell you a lot about your personality . See ? It says that an Aries is energetic and loves to socialize . 
 Person1:        Well , you certainly match those criteria , but they ’ re so broad they could apply to anyone . What does it say about me ? 
 Person2:A Capricorn is serious-minded and practical . She likes to do things in conventional ways . That sounds just like you !
