text: Good question weng! Its very hard, but let it go over your head. The fact that he is your boss makes it difficult. Try to feel sorry for him that he is so insecure that he has to be arrogant. We cant like everyone all of the time. Dont make it a problem for yourself, its his problem let him get on with it. Just do your job and be polite, dont a*s e lick, just be yourself.... Your boss will probably appreciate that more.  Get to know what makes him tick and concentrate on that. If he does or says anything you dont like just be assertive without being rude. Its not what you say but how you say it that matters!  I hope that you are happy in your job. If your boss affects your happiness in your work, then it may be best that you look for another job.  I hope it does not come to that stage. Try not to let his arrogance get to you, alot of people are like this.
