question:
Person1: I'm really fed up with Larry ! He's the biggest airhead I've ever met.He always makes careless mistakes , and he's a pain to work with .
Person2:You shouldn't be so negative.You ' ll always have some co-workers that are harder to work with than others.But if you are negative and start name-calling in the office , it will make a bad working environment for everybody .
Person1: You only say that because you don't have to work with him.The people in your department seem so capable and nice to be around.Take Mary for example.She ' s smart and enthusiastic . I've never met anyone as cheery as she is .
Person2:Everybody has their strengths and weaknesses.Even Larry.He might be a pain to be around , but he's also very good at staying in budget on projects.Mary , on the other hand , spends our project money like there's no tomorrow.Also , she's never willing to stay a little later at the office.She always leaves at 5pm sharp .
Person1: Isn't there anyone in the office that is a perfect co-worker ? What about Bob ? Everybody loves Bob.Even though he's flesh out of college and still a bit green , he is a great co-worker .
Person2:You're right.He ' s a hard worker , easy to get along with , honest , and he never steals the credit on projects.The only thing he's lacking in is experience .
Person1: Maybe that's why he's so nice !
