question:
Person1: hey , Mary , what's up ?
Person2:not much . Last night I met this great guy at the bar and we had such a wonderful time that we decided to meet again tonight .
Person1: oh , that's exciting . What's this guy like ? Is he hot ?
Person2:well , I didn't think so at first . But as we started talking , I found his extremely funny and witty . I couldn't stop laughing at his jokes ! We have so much in common . We like the same teams , music , a
Person1: it seems you two are a good match . What qualities do you look for in a friend ?
Person2:there's nothing definite I think . I don't have a list or anything , but when I first meet somebody , I can usually tell whether or not that person is going to be a good friend . It seems I have radar h
Person1: well , that's something I've never heard of . But if you as me what I value most in a friend , I would have to say honesty .

question:
Person1: We've got a problem ... it looks like we'll need more spotlights on the exhibition booth . The client thinks it's too dark , and they want to add halogen lighting . We've already got 3 sets of track lighting from you guys , do you think you could help us out and throw in some halogens ?
Person2:Oh ... Um ... I don't think so . you know the halogen lighting is much more expensive than your track lighting system . Plus I'm going to have to call in some guys to install it for you . That's not going to come cheap .
Person1: But it would only be adding to the existing structure . We're not talking about anything new here ...
Person2:It doesn't matter because we will still have to call the electrician out , and they are union labor . It'll cost you a pretty penny ...
Person1: How much do you think it would cost ?
Person2:Mumm , I estimate it'll run in the neighborhood of ... $ 500 per light .
Person1: $ 500per light ? ! That's ridiculous ! It can't possibly be that expansive !
Person2:It is , I'll tell you why . We'll have to call in the electrician , he's going to charge overtime now because it's already 5PM , and it will probably take him an hour a light . Plus , the halogen lights take more electricity , so your electrical cost is going to be higher as well .
Person1: Can't you give me a break on this ? We've already spent so much money on lighting , I hate to have to blow so much more on halogens .
Person2:No , that's the cost , and that's what it's going to cost us . We can't go in the hole with this . I am giving you my best price , so take it , or leave it .
