Person A -
Person A is a simple and very pleasant person. She doesn't get upset easily and generally doesn't overreact. Doesn't show much anger or unpleasantness. She laughs a lot and has more fun at work than at home and (seemingly) likes to socialize in the work place. Will still do her work well. Fairly generous and thoughtful of others, friendly. Seemingly more energized around bigger crowds. Can get into arguments sometimes but this is somewhat rare. Concerned for those who are close to her. Simple, not flamboyant. Really likes reading, mainly novels. Enjoys watching TV also, likes sitcoms.
Person B -
Person B is quite introverted. In fact, he told me once that he didn't like functions with a lot of people, and I agreed with him. He doesn't like to be the center of attention, and generally doesn't talk a lot. More comfortable around close friends/family. Dealt with quite a few personal problems around him when he was a kid. Can seem indiscreet or nasty at times. Not the nicest person in the world. Quite hard-working, and he travels around the world a considerable amount (for his job). Likes to talk about some of the issues/problems he deals with at his job, and also likes to talk about his travels. He once was talking about how food in China is very different from the Chinese food in America (possible Si perhaps?). Cares about what others think of him. Doesn't express his emotions easily or at all. Speaks in a monotone voice.
Person C -
Person C is a good guy, and multi-talented. He plays the piano very well, and often plays when he's feeling down or to entertain others. Can be a very funny and witty guy, and likes to crack jokes and make people laugh (people he knows well usually). Honestly I'm not sure if he's extroverted or introverted, I think it's close in that regard. His interests lean toward introversion. Likes to read a lot, and was very good in math as a student. He is interested in mathematical theory. Also interested in philosophy and politics and loves to have discussions about these sorts of things. He has changed jobs and interests quite a few times. Likes playing board games, likes to be neat around the house, and takes a shower immediately after waking up (even if it's a weekend).
