That's funny, I was talking about that subject with a close friend in the afternoon. I made him discover the MBTI months ago. I asked him today "so now tell me your type !"
He is an ISFP and used to go party and does not like being alone.
I am an extrovert, I love being by myself. I can talk very long time, then just remain quiet , read or watch a movie, go for some artistic work...ect
I am always thinking about what is important to me probably my (Fi) and I love to share it with other people I trust.
When I talk I can take the chance to know my feelings better. It has not always been the case... When I was younger I used to talk to be noticed, to seduce, to provoke, ...etc.
I don't like super high energy clubs, parties or noisy atmospheres. Most of my friends are introverts. Very talkative people are to me some energetic vampires.
Most of the time those people don't have the talent to listen to you carefully. Also, sometimes, some of them don't even listen to themselves...
I work by night so I'm free to choose my daytime relationship as I want to. I've chosen this rhythm and "quiet nights" because I had been unfairly treated by some arrogant clients in my ex jobs
and I had refused to shut my mouth. I was not the kind to be peaceful with those no values and "I give you when I want my shit people".
So I've decided to change my job + my way of living. That's a rhythm that I truly enjoy.
My best friends are my milk

and I have a very deep, special and unic relationship with each of them (most are male).
Intellectual activities and books are my bread. If I don't read for more than 24 hours I don't feel good with myself.
I don't like groups generally speaking unless I am acknowledged for my unic personality and talents in a friendship atmosphere.
I am very sensitive to atmospheres, that is to say negative feelings exhaust me very easily.
I love that feeling of being into a bubble with another close person. I've noticed that all my friends have more or less the same qualities.
When meeting new people I observe with care their reactions and body language.
In this case, I don't talk that much to be sure I am feeling who they are on the spot. I notice who in sincere, who is shy, who is the chief, who is clever, who is fair/unfair, gentle, asshole...etc.
When I was young I used to joke around without paying too much attention to other things.
I am very careful with my relationships, I don't wanna be in touch with just anyone and lose my time. Moreover I want to know why I'm in touch with X or Y.
To me there is no "by chance". There is always a good (or a frightening) reason why we keep on meeting someone.
And I wanna know where I stand.
