Q: Person1: Did you hear the news ? Two of our major suppliers , Murphy Music and U-Tunes are merging ! If they are conglomerated into one company into one company , it would have some serious affects on our market strategy .
Person2:Are you sure ? Who told you that ? I highly doubt that they would take the step to merge into one company ... They're supposed to be bitter enemies , the strictest of competitors.It must be a rumor.It can't be true .
Person1: I read it myself on the financial page.They ' re really going to join together . U-Tunes was bought out by Murphy's , they will take over the company as of next month .
Person2:The competition must have been too stiff for U-Tunes.Otherwise why would they allow themselves to be taken over by their sworn enemy ?
Person1: I guess they must have figured it would be easier to merge than to keep up the cutthroat competition.If you can't beat'em , join'em .

Q: Person1: Why is the long face ?
Person2:I'm getting sick of work man . I can't take the political bull in the company any more .
Person1: Did you just get your review or something ?

Person1: That sucks .
Person2:I'm just pissed that management can't see behind his smooth talking lies .
Person1: Look on the bright side . At least you have a job .
Person2:Yeah . I shouldn't stress about this anymore . It's not like I can do anything about it .
Person1: Exactly . Instead , we should have some drinks tonight .
