Person2:To be honest , it was horrible ! My manager is such a pain in the neck !
Person1: Why ? What happened ?
Person2:Well , he made quite a few mistakes on the monthly report and when his supervisor found them , my manager blamed them on me !
Person1: That's not very fair . What did you do ?

Person1: Does he treat everyone in your department like this ?
Person2:He treats everyone pretty badly , but the way he treats me really takes the cake !

Person2:I really have no idea . All I know is that the thought of him really curls my hair !

Person2:Not really . I'm hoping to live with it for a while until I get a promotion .
Person1: That's very sensible . It sounds like you have a good head on your shoulders .
Person2:I try to be sensible about it , but it's not very easy . Sometimes you just have to grin and bear it .
