people in the workplace

     since entering into society,i have found ,there are many many things i have to study.especially ,the interpersonal.in the workplace ,there are kinds of people ,defferent character.sometime,when i am  insufficient about something or someone.i always point out straightly.as a newcomer in the company,something ,something work i could not do it ,and then certainly,it needs several department's coordination and support.however,some department's colleague looks like so reluctant.what can i do ?yeah,i could not keep silent.but ,maybe the only thing i can do is keeping silent.no ,today ,i meet a colleague who did not look like kindly .i am angry .however,i tell myself,people in the workplace could not be too impulsive.maybe i must learn to adapt to the society.
