Personality tests. :)

My mom got a personality type book to teach a careers class at a homeschool co-op. But being the personality type she is, she had to test everyone in our family. We have a mixture of every personality type in our house.

D=Dominance: Direct and to the point, decisive and bottom line oriented. These people tend to be independent and results driven. They are strong-willed people who enjoy challenges, taking action, and immediate results.

Which is the same as "Choleric":

A person who is choleric is a do-er. They have a lot of ambition, energy, and passion, and try to instill it in others. They can dominate people of other temperaments, especially phlegmatic types. Many great charismatic military and political figures were choleric. They like to be leaders and in charge of everything. They can be very manipulative.

My dad and one of my sisters is a D.

I=Influence: Optimistic and outgoing. Often highly social and out going. They prefer participating on teams, sharing thoughts, and entertaining and energizing others.

I's are the same as "Sanguine":

The Sanguine temperament personality is fairly extroverted. People of a sanguine temperament tend to enjoy social gatherings, making new friends and tend to be boisterous. They are usually quite creative and often daydream. However, some alone time is crucial for those of this temperament. Sanguine can also mean very sensitive, compassionate and thoughtful. Sanguine personalities generally struggle with following tasks all the way through, are chronically late, and tend to be forgetful and sometimes a little sarcastic. Often, when pursuing a new hobby, interest is lost quickly when it ceases to be engaging or fun. They are very much people persons. They are talkative and not shy. People of sanguine temperament can often be emotional.

We have two I's in our house. They just about drive the rest of us insane...

S=Steadiness: Empathetic & Cooperative. Typically team players and are supportive and helpful to others. They prefer being behind the scene, working in consistent and predictable ways. They are often good listeners and avoid change and conflict.

S's are the same as "Phlegmatic":

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, calm, rational, curious, and observant, making them good administrators. They can also be very passive-aggressive.

We have a few S's. In our house, they make things flow smoothly. We love our S's.

C=Conscientiousness: Concerned, Cautious & Correct. These individuals are often focused on details and quality. They plan ahead, constantly check for accuracy, and what to know "how" and "why".

C's are the same as "Melancholic":

A person who is a thoughtful ponderer has a melancholic disposition. Often very considerate and get rather worried when they could not be on time for events, melancholics can be highly creative in activities such as poetry and art - and can become preoccupied with the tragedy and cruelty in the world. A melancholic is also often a perfectionist. They are often self-reliant and independent; 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.

As far as we can tell at the moment. I'm the only "C" in the house. Which can make some pretty tense moments. No one seems to understand why it matters to me that there is a "t" on the end of "kept". Or why I would care to know that there is a certain kind of snake that can digest it's own heart to stay alive.
