Based on my experience in relationship, I figure out that there are three types of human characteristics, logic, socialize and arts. These three characters need to be known to keep your relationship.
Logic person is a logical type of person. The characteristic of this person are firm, calculative and most of the time thinks systematically to achieve their goals and needs. They sometimes hide their feeling and emotion in some situations.
Socialize type of person usually can be noticed by their ability to be flexible in some situations. Other characteristic of social type person is that person is extrovert and talkative. They are comfortable to share stories and experience to others. We can see their moods, emotion and feeling easily.
The last character is art person. Art person is usually moody. Their feeling and emotion are hard to be known because the moods are easy to change in minutes. Most of the art type persons are really have good taste of art if he/she is in a good mood situation. Their moods sometimes blind their emotion and feeling. Therefore, others may consider art persons are ignorance.
Humans have combination of these three types of characters. However, one character is dominant to the other two. To keep relationship, we need to recognize our own characteristic and others characters. Then we will have more understanding and tolerance to ourselves and other people especially to whom we are close with.
