Input:  Person1:     Jane ! What an enchanting skirt you have on !  
 Person2:  Thank you ! Guess how much it costs .  
 Person1:      Bright colors , smooth material , exquisite craftsmanship , soft lines ... Darling , it looks elegant on you ! It can't be any cheap stuff . Something around two hundred , I guess .  
 Person2:  Your offer is way off the mark . It set me back only sixty-five .  
 Person1:      Then you got a windfall ! Was sixty-five the original price , or did you get a special discount ?  
 Person2:  Neither . I drove a hard bargain with the vendor before I got the price down .  
 Person1:      How much did she ask for ?  
 Person2:  Three hundred ! That's daylight robbery . How dare she play tricks on an old hand like me ? Without hesitation , I gave my offer---no more than fifty .  
 Person1:      She must be fuming with anger at such a bid , wasn't she ?  
 Person2:  Not at all ! She's really been around , and seemed quite accustomed to bargaining like this . That's the trade . She only demanded a higher bid , saying the purchase price was even higher than seventy . She was lying ! Then I inquired , ' May I have it at sixty ? ' she waved her head .  
 Person1:      Then you pretended to go without buying it ?  
 Person2:  Yeah . I turned around and started to move out . Just then , she yelped behind my back , ' all right , all right ! I may sacrifice a little . Let's fix it sixty-five ! Can't be cheaper . '
