Using another temperament test based on 4 animals, I am a panther in many ways, which indicates that when there is a task at hand, I concentrate on that task to the exclusion of other things. Doesn't mean other things are not important, it just means that at that particular time, they aren't. A dolphin, who is generally a more play-centered person, looks to have fun at all times. A peacock wants attention. An owl will think about a task, examining all angles. If a dolphin type came to me during a task and started goofing around, preventing me from working and meeting a deadline, I might snap at them at that time, whereas another time when job pressure was off, I would not. A peacock might be offended by not acknowledging their contribution when all I see is that the task is done. I might get annoyed with an owl because they were not actively working.
All this is to say that each person may experience another person's words or actions through a filter which inaccurately interprets that person's motives or meanings. Knowing temperaments can be a general guide to understanding another person. Of course, there are numerous shades and nuances of any personality type.
