Trust is the basis for effective

Trust is the cornerstone for effective communication.

And prejudice is the enemy of communication.

But how to build trust if someone has prejudice against you?

He won't listen to you and everything you have done can be misunderstood and you are like two persons from different world!

Too difficult to change this! 

Prejudice and emotions can easily affect the way you talk.

And you even lack the courage to talk to him again because you know he will definitely hurt you with words.

Treat him like you do with others, and you do the best to control your mood.

If it still doesn't work, just let it go as it does.

No need to push yourself for such a guy because he is not worthy it.

PS: this guy is an unmarried  35+ male colleague who is good at sophistry. 

PPS: I just got a tense quarrel with him in front of my boss and I feel super wronged.
