I'm thinking of having a fight with my coworker.
Why? What did your coworker do wrong?
He is such a telling ass, always tattling on me at work.
People don't have to friends with the people they work with and it is understandable that you might not like them, however you shouldn't fight them. It could get you in serious trouble.
It's fine. We work together after all.
I'm glad that you have worked on your issues with your coworker. I do hope that next time you have a misunderstanding or conflict with someone, your next move should be trying to resolve it and not immediately turn to fights.
