Four temperaments

Four temperaments are four types of personalities.
Temperaments describe how people tend to act in different situations.
For example, if you are the kind of person who speaks up easily and likes to try new things, then you have a temperament called 'Sanguine'.
If you are the kind of person who likes to think things through before speaking and enjoys having a plan, then you have a temperament called 'Phlegmatic'.
If you are the kind of person who's always thinking and likes to try to fix things, then you have a temperament called 'Choleric'.
Finally, if you are the kind of person who likes to help other people and makes decisions based on how others feel, then you have a temperament called 'Melancholic'.
So the four temperaments help people understand different types of people, and what they do in different situations.
