Person2: That's easy . Everyone knows that there are nine . 
Person1:     Not anymore ! Can you believe it ? They've decided that Pluto is not a planet anymore ! 
Person2: Nice try . I wasn't born yesterday , you know . 
Person1:     I'm dead serious . They've decided that it's too small to be a planet , but actually they haven't yet agreed on how big something has to be in order to be a planet anymore . 
Person2: That sounds crazy . But they can't just change their mind about things like that . 
Person1:     Yes , they can . If you remember correctly , people used to believe that the world was flat . 
Person2: I suppose you're right . They also used to think that they were so important that the sun revolved around them , not the other way around . 
Person1:     We actually know relatively little about space and the cosmos . 
Person2: Do you think that we'll one day be able to travel to another planet for a vacation ? 
Person1:     I suppose we could actually live on a planet outside of the milky way . 
Person2: Do you think we'll ever get to meet an alien from outer space ? 
Person1:     I hope not . I think they would be a threat to those of us that lived on the Earth . 
Person2: You're so old-fashioned . That's what people used to think about people from another country ! 
Person1:     Point taken . Hopefully one day , we'll live in an interplanetary society .
