I just lost my temper. I cussed out a co-worker because he asked me about an issue that I thought had been resolved by our boss. I completely lost it. I yelled at him, "What are you, f**king crazy?!" And on and on. Then the boss got on the phone and explained that she had changed her mind and the co-worker was just asking me how I wanted to handle her new order.
I apologized to him.
Now I feel bad. I almost never do this. It's the first time I've lost my temper in eight years on this job. Why did I get angry? Why did I attack him with profanity? Why didn't I calmly get the facts and then explain my position to him?
It was not my finest moment. I will learn something from this.
UPDATE: I felt so bad about yelling at my co-worker that I went outside and beat the crap out of the first guy I saw. So it turned out to be an okay day after all.
