I agree with you that my categorization is questionable, and subjective. The comments here make it clear to me that different people process things differently, and even give different names to similar feelings.

You can be happy and feel fear, or be happy and excited.

Well, happy and excited seems to be almost the same thing. While happy and fear - I don't think I ever felt that way in my life.

I wanted to see more about this distinction and found a relevant Wiki page about emotions [1].

"Confusion" appears to be added as a separate emotion in some classifications, while missing from others. When it's added it is added as a neutral emotion (having 0 emotional "tone").

Personally, don't think I experience confusion as an emotion. It's just a mental picture of my state and emotions arise according to how I interpret that picture. Same as "I am lost" or "I am missing a finger" are not emotions, thou they would cause emotions to arise.

I don't know if shell scripts should be considered a programming language.

What a snarky reply. Don't know if you get off on things like that, but I hope it increased your mood.

Perhaps you can see a parallel to your comment? And I do get off on things like that, thank you!

I didn't see any snark? He's making an interesting point, if an oblique one.
