Advice
I dealt with many people who were very rude and simple unkind, but I refrained from returning that kind of behavior and it kept me out of trouble. Additionally, at the end of the job, my employer thanked my brother and I because he was told by many people that we were very kind, hard working and respectful young men.
My advice is this; no matter how difficult it may be to work with someone, always show the love of Christ and never sacrifice your character for revenge or for the sake of petty arguments.
