 Person1:       Ok , I ’ Ve got an up-to-day map . Let ’ s check the route from here to the airport . 
 Person2:Where are we ? Oh , here we are . So we drive to the A120 and turn left . 
 Person1:        No , we turn right . Remember that we are coming from this direction . 
 Person2:Oh yes ! Sorry ! Then we drive to the M11 motorway . 
 Person1:        How far is that ? 
 Person2:It ’ s only seven miles . We turn left to join the motorway and drive south . 
 Person1:        According to the map , we get off the M11 at the second junction and join the M25 . That ’ s the motorway that goes around the edge of London . 
 Person2:That ’ s another 15 miles , so that ’ s 22 miles total so far . 
 Person1:        Then we drive west on the M25 . we must be careful to turn in the right direction ! 
 Person2:Then we drive on the M25 . it turns south . When we reach exit 15 , we turn left and go west along the M4 . 
 Person1:        Then we take the first Heathrow Airport . What ’ s the total distance ? 
 Person2:The journey around the M25 is 33 miles and then 3 extra miles to get to the airport . So how many miles is that together ? 
 Person1:        22 miles to the M25 , 33 miles on the M25 , and 3 after that . That ’ s a total of 58 miles , isn ’ t it ? 
 Person2:It shouldn ’ t take us very long to cover that distance . Remember that we can go quite fast on the motor way . 
 Person1:        We can only go fast on the motor ways if there isn ’ t much traffic . I think we should allow ourselves plenty of time to get there . Being early is much better than being late . 
informal

 Person1:       God , I didn ’ t realize . I didn ’ t , I didn ’ t know ...  
 Person2:... Who you were with ? I didn ’ t know whom you were with .  
 Person1:        Excuse me ?  
 Person2:Sorry , it ’ s from the Godfather . It ’ s when the , when the movie producer realizes Tom Higgins had emissary of Vito Corleone , it ’ s just before the horse ’ s head ends up in the bed with all the bloody sheets , you know , wakes up , and AAAL ! Never mind .  
 Person1:        You were spying on me , weren ’ t you ? You probably rented those children .  
 Person2:Why would I spy on you ?  
 Person1:        Because I am your competition which you know perfectly well , or you would not put up that sign just around the corner .  
 Person2:The entrance to our store is around the corner . And there ’ s no other way of saying that . It ’ s not the name of our store . It ’ s where it is . And you do not own the phrase around the corner .  
 Person1:        What is that ? What are you doing ? You ’ re taking all the caviar ! That caviar is a garnish ?  
 Person2:Look , the reason I came into your store is because I was spending the day with Annabell and matt . And I was buying them presents . I ’ m the type of guy who likes to buy his way into the hearts of children who are his relative . And there ’ s only one place to find a children ’ s book in the neighborhood . That will not always be the case . And it was yours . And it is a charming little bookstore . You probably sell what 350,000 worth of books in a year .

 Person1:       It is obvious that their government is nursing the hope of having all other countries over a barrel and bring them completely under their control . 
 Person2:It ’ s a typical of them to do so . 
 Person1:        What can we do ? 
 Person2:We must keep developing our economy and unite with other developing countries to fight against it .
