I had thought about that possibility, or the possibility that the conversation that he wrote isn't exactly as it went. But I think that the conversation that he decided to write in the article is a reflection of his own mental processes. That is actually more telling about how he sees his manager than an actual conversation would be.

If, in the actual conversation, the manager tried to explain his point of view and the author instead made the manager out to be a buffoon in his story, I think it's indicative that he either (1) doesn't listen well (and therefor didn't recall what the manager said) or (2) doesn't respect his managers.
