Here's his biography:
http://en.wikipedia.org/wiki/Louis_MacNeice

in case you are interested enough... That was a good point about the very prominent Te. I don't know if you are at all into poetry, but look up something by him ("Snow", "Sunlight on the Garden", "Meeting Point" or "Prayer Before Birth") and see if that gives you a clue. It may not. He was quite a diverse poet. I would lean toward either ESTJ or ENTJ for him, I don't see him as a introvert based on his life. I could see him as an Intuitive but he just seems a little more grounded in the real world somehow - a lot of his poems are very strong on sensual detail. "Susceptible for physical impressions."
I've been thinking about MBTI types of some of my fav authors (especially poets) lately and just thought I'd ask you about this one. No pressure though.
I just read a bunch of stuff about him (mostly on poetryfoundation.org), and some of his poems (which I LOVED) -- and I could see ESTJ.

Mostly because I don't see any Ni in what I read about him. My initial thought of "Why would an ESTJ want to be a poet?" went away when I saw, in the article I read about him, that he used poetry almost like a journalist would use an op-ed piece. He saw things that he thought needed to be said, perhaps things that were wrong, and pointed them out to everyone. Also, seeing poetry as a craft, that you could perfect -- something with outside standards -- seems more Si/Te.
So yeah, I think you have my type endorsement! I could have also seen ISTJ (because I didn't see anything that made him look more like an extrovert), but I trust your judgment.
Oh, and [MENTION=6166]Orobas[/MENTION], before I begin I'll just say that your usage of the phrase "friendly (and) business minded" is accurate in more ways than just with subordinates at work. My default mode, with people I don't know, is friendly and civil -- maybe not business-minded unless there's actual business to attend to, but still. I bring this up because it's good background for my responses to your hypothetical scenarios, below:
1. A bit of hyper emo-like saying "Hi!" in a kinda spastic silly way with a big funny grin.
If I didn't know you well: I would probably smile (maybe laugh) and say hi back. Wouldn't be freaked out or anything, but might be a little bit surprised, and would definitely put it into my Si bank as a character reference for you (i.e. that you have a tendency to be goofy/hyper -- which isn't necessarily a bad thing).
If I did know you well: I would grin and cheesily wave and say hi back :hi:
2. Being a bit too spastic or emotionally invested when talking about a logical plan or issue-thus giving off an angsty or emo vibe or tone to my voice.
If I didn't know you well: I might be put off/irritated by that, but I would react by going full Te on you -- not in the form of a Te bitchslap but removing all pretensions and cushioning of blunt statements. The purpose of this would be to turn the environment into an all-facts atmosphere -- thereby (hopefully) diffusing any possibly explosive situation. When people get (seemingly) disproportionately emotional about things, I start to feel like the person is a bit of a loose cannon, i.e. that I can't really predict when they'll get emotional. Hence the reaction of "I'd better calm this person down because who knows what they'll do next?"
If I did know you well: I would still go completely Te on you, but I would be more gentle and understanding once you had calmed down.
3. Sharing of inquiring about value based topics inadvertantly. Like if the ESTJ said "I had I long weekend", I might go "Oh really, that sounds terrible, what happened?" not in a planned way, but almost as an automatic reply
This is an interesting one because I think it's different with ESTJs, maybe. Generally I wouldn't (and I don't think other ESTJs would) make any statements like that unless I was ready to give an answer of some kind. So regardless of whether I knew you well or not, I would answer you honestly, and the only difference would be the level of detail.
(Or any thoughts you might have regarding business interactions in general)
Earlier, I used the word "know" in lieu of suggesting friendship, because those reactions would apply in a work setting if I worked with you enough to feel like I understood you and got along with you well -- even if we didn't necessarily hang out after work.
Back to your original post now that I understand what you were referring to:
How do you guys deal with emotional overtures/emotional spacticity from others?
I find I have to tone down my emotional intensity around ESTJs-like it isnt translating properly, so they dont understand how to respond.
With people we don't know, emotional intensity can be kind of alarming -- and depending on the situation, it can strike us as being annoying, because keep in mind, Fi outbursts are what we fear/hate more than almost anything in the world.
Relevant quote from "Was That Really Me?" by Naomi Quenk:
"From a(n extroverted) Thinking point of view, the eruption of 'illogical,' uncontrolled, and disorderly feelings is like being at the mercy of strange and overwhelming forces that threaten a person's equilibrium, if not his or her whole existence".
Meaning: if we personally had reacted so emotionally to something, we would see that outburst as the victory of emotion over self-restraint -- something we see personally as anathema, and contrary to everything we value as "mature adults". So from my experience with the xNFPs I know, there's always a point when I've known them for a while, when I started seeing their emotional outbursts as "immature" because I'm holding them to the standard that I hold myself to -- when I should realize that they just react to things differently than I do, and it's not "wrong" for them to do that.
We can NeTe interact all day long however and I work exceptionally well with ESTJs, but it doesnt transfer very well into closer interactions-yet after the fact or when intoxicated, they admit how much they like me. Lots of interesting exploration of ideas, and planning and base value agreement on how things should work, but not really past superficial friendships.
ESTJs like to know for certain that their environment is safe, before they open up. And if they don't feel like they understand you, and feel like your emotions are unpredictable and volatile, they'll probably feel like they have to be "the calm one" in the relationship until they get a feel for how you react to certain things. This wasn't necessarily the situation with my longtime ENFP friend -- as she's an exception to the rule due to having well-developed Te and also being a very self-controlled 2w3 -- but I'm currently in this situation with my INFP friend. She's opened up to me before, and I've dipped my toe into the water and very, very slightly opened up back, only to be met with a reaction completely contrary to what I expected, a reaction never explained to me and never discussed again. This sort of situation can convince ESTJs that as of now, they aren't well-suited to being close friends with the person (as they obviously didn't understand or relate to the ESTJ's deeper inner workings), and that they should therefore back off for a while.
Not that the above situation has happened with you -- but it's a sample of bewildered ESTJ-ness in the face of unpredictable people. So I guess my answer is, in short, that ESTJs just take a while to open up, and given time and a safe space, you can be close friends with them
Hope that helped!
