2)at her worse, I find her to be stubborn, she tends to get overwhelmed by new ideas. She's always hugging people (only her friends though) and telling them how much she loves them and how she's going to miss them. I remember one time at Tropical Smoothie, Our friend and I wanted to go get go get food as we already found a place to sit, we both went to go leave and she was like "No stay, I don't want to be alone" The other friend who likes to be alone and tested INTP (and I he fits the description) as well was like "We're going down stairs to get food, we'll be right back" he ended up giving me the money and I ordered for him. She's a very talented opera singer, and loves performing (but I can see how people from all types could be that). She has a very addictive personality, I don't think that would apply strictly to a type. She loves gay men (but really what girl doesn't?), and she was upset when she found dumbledore was gay because she had a crush on him. She has a habit of getting into abusive relationships, she can sometimes annoy me. When I'm at home from school and she is aswell we meet at Borders which is a 30 minute drive. In highschool I'd be on my way and she'd call and I'd be five minutes away and she'd be like I changed my mind I don't want to anything. She'll promise me something but then won't follow through. She has a terrible sense of direction, she'd get lost if their wasn't either someone else in the car or someone she could follow. She likes to bake and decorate cakes, and they're pretty. She's a perfectionist. We both have the same taste in guys, we both like the same tv shows. I've known her so long I can't say why I like her, except she's a good friend and we look out for each other.
3.)She tends to pass judgements on what people are wearing, or whatever random things. Lately she's been philosphizing more then she use to, In the past I would try to philosophize with her and it wouldn't work. She's always asking what song lyrics mean, about how fat she is and how skinny people are happy. Even though I try to tell her that she'll never be happy with that outlook on life. She picks stuff based on aesthetics more then function. Our other friend and I will be like "ummm ok. But what's it for/ couldn't you have just done that instead" she's like "yeah but it's pretty, see" then points out something on it. I can be like this but I normally only do that if the product isn't expensive. She asked us how to talk to the bank teller once. I don't know how to answer that um just talk. and We were right their, and the lady was staring at us.
I'll add more if I think of it. Also I think I was sleep deprived so she could be INTP, the more I think about it I can see how she can fit. She's defiently on the border for some. but my brain with lack of sleep thinks every thing's a conspiracy, and all tests lie and our wrong.
Okay, maybe I'm way off here... this is just a working hypothesis...
Are you sure you think she's a Sensor? Sensors are usually more content than restless, live in the moment, dislike sacrificing for future goals. Here are a few N characteristics that seem to fit your friend well:
1) restless and insecure (always comparing her weight, for example, to others, doesn't want to be left alone in public).
2) you say she's intelligent but yet you're frustrated that you always have to help her with common sense things (working the computer, talking to the bank teller, directions while driving).
3) she seems to be a dreamer - you say she is often overwhelmed by ideas. A lot of intuitives will feel a strong pull or attraction to something, begin to idealize it, and will then become stubborn when others point out any negative aspects or attempt to steer them back to reality. For example, if she is an intuitive, she may feel a strong attraction to pharmacy for the reason you mentioned earlier or some other reason, convince herself it is the perfect career for her even if it isn't, and mold herself into that career, putting on her "pharmacy" personality at school. Does her personality tend to change depending on the person she's with or the place she's in?
4) Having a crush on a fictional character and then being so upset to find out he is gay is not a down-to-earth, rational thought. It sounds very N, especially NF, to me.
5) She tested as an N, so it's likely she is one.
Everything you have said about your friend screams NF to me, not just based on the temperament description but based on NFs in my family and NF friends.
Also, you said you share the same interests in guys and TV shows. Since you think you are an NF, that would make you both NFs and might explain why. It would be very possible for you both to be NFs and still be very different in many ways.
Here are some excerpts from the book "Do What You Are" regarding NF temperament and weaknesses:
"Idealists (NFs) have a tendency to make decisions based exclusively on their own personal likes and dislikes." (reminded me of her buying habits)
"They have a great capacity for self-reproach. Sometimes they will sacrifice their own opinion for the sake of harmony. At their worst, they can be moody, unpredictable, and overemotional."
What are your thoughts on this? Any way she might really be an N like she says, just an NF instead of an NT?
