history: My coworker received a promotion over me. I am envious of his newfound success. I can understand why you might be jealous of your coworker. I would try to keep your head up. I'm not jealous of my co-worker though?  What makes you think i'm jealous? You said that you were envious of his promotion. It is understandable though.
current: I didn't say that.
next: Okay, I am glad to hear that you are no longer feeling jealous.
