[EX Q]: Person1: Guess what ! I know something you don't know !
Person2: What's that ?
Person1: How many planets are there in the solar system ?
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 .

Person1: That's too bad , anyway , I'm sure things will turn around next master .
