Sanguine
Sanguine, what's that? an animal? oh, no.. it's penguin.. (haaa,,boring jokes if I should say it myself) Then, what's Sanguine? as the title say, I'm talking about humans temperament here... so, as I read in a book (My Freshman Enrichment Program books?? I don't remember where I read it but it sure is have been discussed in my CB (Character Building) Class.) Sanguine is a type of people that you can maybe say easy-going. So, as you usually see an easy-going person is the one with sooooo fucking awesome many friends. Yeah, it's like their motto is "Friends everywhere eyes can see".. But, a person with this temperament easily getting bored with their hobby..Why?? Please, don't ask me...I'm not a Psychologist. It's a pity that I'm not this one, cause I'm not the one with many friends..hahaha
Choleric
Now, Choleric. It's not Cholera kay.. again, a very good trait for you with this temperament. I say this is the one with a leader aura, charismatic, etc etc blah blah blah... They tend to like being a Leader and is charge of everything...(WTF?!) The one in Wikipedia even say that they can dominate people of other temperaments, especially phlegmatic types. hwew..
Melancholic
Melancholic is often a perfectionist... Maybe some of you already know what a perfectionist is, but whatever. It's people that feel uncomfortable with a half-assed work.. They want their work to be as perfect as possible. Well, I seldom saw people like that in real life, except television (the worst one at that,, that it often becomes funny..haha). One negative part of being a melancholic is sometimes they can get so involved in what they are doing they forget to think of others. So, if you're a Melancholic then don't forget about your surroundings..hahaPhlegmatic
Phlegmatics tend to be self-content and kind. They can be very accepting and affectionate. They may be very receptive and shy and often prefer stability to uncertainty and change. They are very consistent, relaxed, rational, curious, and observant, making them good administrators . However they can also be very passive aggressive. (Wew, complete copy-paste from Wiki..well, I can't say anything about this one..really, it's complete enough on this..hehe)
