I had an old friend that I used to live with. We kinda hit it off the day we met. She was extremely talkative, prided herself on the grades she made in school, psychoanaylzed everyone, and dated "nerds" and "dorks".
She was incredibly organized and did most things predictably. She took naps during the day after her afternoon class, was really concerned with her weight(but not so much her overall health). She tried to fit into every single group she found on campus. One month she was hanging with the LGBT group, the next, she had joined the hip-hop crew, and then she was going to go into the military because she met some people in the military. She was a psychology major and then a teaching major.
She expressed the occasional anti-establishment sentiment, but then she would turn around and say that people needed the government because they couldn't be trusted. She loved to read and spent a lot of time in her room alone, but she was almost too extroverted for me. I would quietly sneak into our apartment because as soon as she would hear me come into the door, she'd come out of her room and start talking for hours. Most of her conversation consisted of complaints about how people treated her wrong or didn't accept her(her family, her "friends", her boyfriend,etc...). The next day, she'd be happily hanging out with the people that she was talking about until they did something else she didn't like. Then she'd get all dramatic again. I think she broke down crying every week. She had a silly sense of humor. We got along pretty well. Often times, she overwhelmed me with her emotionality and how talkative she was, but she was cool peoples. She test as an ENTJ and an INTJ.
