Here are some first impressions based on two or three times of interaction. I have my own thoughts, but I want to float this out there and see where your heads are at. What type does this sound like?
Hardworking, assertive, straightforward, logical, efficient, judgmental.
More in-depth description:
Works long hours and goes long periods without vacation time. He succeeds in high-pressure environments (might thrive it it, too, but can't tell yet).
Jokes loudly and forcefully at times, more so than I'm comfortable with. And sometime he laughs at things I don't find exactly funny. Like he'll recount how somebody said something funny, or reacted in a funny way to him, and I just don't get it. That makes me feel awkward, and I don't think I respond how he'd prefer. It could be just that he's a bad story-teller, too.
Feelings seem somewhat foreign; he is not emotionally adept or eloquent. He remarked once that one time he got on his roommate's case about household chores, left for awhile, and came back to find his roommate "a basket case," which completely surprised him. He said that was one point where he realized people have different reactions emotionally to things. (I successfully kept myself from doing this )
He has thus developed a sort of skeptical phobia of offending people. It's partly a sort of "why are people like this? It's stupid and illogical" and a fearful feeling of not wanting to push people away or accidentally hurt them.
He recognizes that working hard and being dedicated to greatness has its costs, including relationally. But he seems to crave relationships and friendships anyway, just doesn't know how to get it to happen. That said, he didn't seem to really accept many of my opinions and suggestions on the topic, like when I tried to explain why individuals might be making particular choices (that he disagrees with).
One time I told him that women very often dress up to impress each other more than they do men. He gave me a doubtful look but didn't contradict me outright. Then he went on to talk about how he wished someone would write a book called, "Women, for dummies." I have no idea if my concept stuck at all.
I've had to explain some of the things I said several times, things that seemed obvious to me. For example, that having a solid family helps prepare one for a good marriage / long-term relationship. He just kind of looked at me blankly, then said something like "Sorry, I'm a little dumb. Could you please say that again? I can't understand what you mean." I was kind of flabbergasted for a moment because why would I have to explain that? It's so obvious! How does one break down an innately natural way of thinking or doing? But I tried, using examples and analogies. He got some of the parts of the breakdown, but I'm not sure if the whole original concept got across. At least he patiently listened. That's happened a few times.
Moral / ethical inconsistencies drive him nuts. He told a story about two of his friends, which illustrates this: A heavier weight girl, not obese but not in shape, broke up with her boyfriend because he was overweight. He developed a terrible opinion of that girl, not because of the choice per se but because she was being a hypocrite.
He recounted at different times examples of him saying what he really thought getting him into relational trouble, which seemed mostly puzzling to him.
He said he'd stop hanging out with anyone who'd ever done drugs (at which point I tried not to go ). Doesn't like art (can't tell yet if that's lack of proper exposure or actual dislike - I hope the former). Doesn't consider himself sharp-witted. Really good at math, though that could be practice.
Good at physically demanding things, like sports and fitness. Considers himself a germaphobe. Reacts badly to people who invade his personal space.
Has a lot of disdain for people who don't know what they are doing. Will plainly say he thinks people are idiots or incompetent.
