I'm curious as to what you guys would say about the following guy.
To start, he can be very argumentive. When he does this, he can get firey and agressive. It's not uncommon for him to start kicking or hitting things when this happens. He generally doesn't show emotion, but when you spark the right thing, it sets him off and he gets verbally (even physically) confrontantional. He can be somewhat contentious, but he's not even a very big guy. He will start to pick fights with people bigger than him, and he does this as sort of a "test" to see what kind of reaction he can get.
He can also get into trouble with his drinking. He may go out to bars, and not know when to stop. This of course can lead to further problems with his temper.
One good quality is that he always seems to know what to do and where to go. He has a habit of ending up in the right place with good timing when others look lost. He can also seem calm when pressure is put on and never gets distracted when he is in a concentrated mode.
So from a brief discription like this, can you already tell the person's type?
