Input:  Person1:     Oh , my God ! I've been cheated ! 
 Person2:  What ? What did you buy ? 
 Person1:      It's a brick ! I can't believe how stupid I was . Damn it ! 
 Person2:  What is it ? Why did you buy a brick ? 
 Person1:      There was a guy on the sidewalk.He had three new boxes , Panasonic video camera boxes.He said he had to get rid of them quick . 
 Person2:  And ? 
 Person1:      So he said he'd sell me one for twenty dollars . A four-hundred-dollar camera for twenty bucks . 
 Person2:  And it's a brick ? 
 Person1:      Yes . 
 Person2:  I can't believe how stupid you are . Why didn't you open the box ? 
 Person1:      I wanted to . But he said , no , the box is still in its plastic wrap from the store.If it's opened , other people won't believe it's new . 
 Person2:  So he had the boxes wrapped in plastic . 
 Person1:      Yes , it was the kind of perfect plastic wrap that comes with new products.Look , it even had a bar-code price sticker on it ! It looked brand new . 
 Person2:  But why would a guy be selling new video cameras for twenty dollars ? 
 Person1:      He said he had to get rid of them . They were stolen . 
 Person2:  Aha ! Now I understand.You were trying to buy stolen goods on the sidewalk.So , what I think is , you deserve to get cheated ! 
 Person1:      C'mon , don't blame me ! I thought it was a new camera . We could use it.We were even thinking about buying a camera . I don't understand how he could have such a perfect-looking box . 
 Person2:  That's no problem.He just has a friend who works in a shop that can do plastic wrap . That's easy.And probably it's the same shop he got the boxes from.Maybe his friend works in an electronics store . They sell video cameras there . Probably they had a couple video camera boxes lying around.So they get the idea of wrapping bricks to sell to fools like you.Twenty dollars a brick . That's a good profit if they can sell enough bricks . 
 Person1:      You're right , Sarah . I was a fool . I can't believe it . How could I fall for such a trick ?
