I had a lot of different sides as a child. I recall when I was about 8-10 being really loud, thrill seeking, and clumsy and I introverted once in awhile by playing RPGs like Legend of Zelda, FFI, and Dragon Warrior.
From 11-12, my friends and I would often play make believe games like being ninjas and having mock swordfights, and mapping out territories or devising with various 'inventions'. I also liked to draw various heroes of stories and write about them, and draw vehicles and other things and give them life through imagination. I formed a club composed of about 8 different boys, and we would form different types of games and ceremonies and do club stuff. I was pretty bossy, but really good at thinking of ideas for stuff the club could do, and would order my underlings to carry out my plans. The jocks liked to try and foil our plans once in awhile but we had fun. I had an uncle who tried to get me into sports, but I was AWFUL at them because I had trouble regulating my attention (I would sometimes drift off into my inner world at a critical moment, or just not care enough about the game to try really hard), hockey and baseball werent my friends, though I was good at short distance sprinting, high jump, and long jump.
When I was 13 I had the most terrible year of my life, I was sent to live with my grandmother and enrolled in a white christian school (keep in mind I was an athiest), I listed my faith as protestent thinking protestant meant someone who protests the church. Needless to say I was never popular, and I had a few strange experiences with girls and no friends (at one time I was hickeyed up by a girl in a most aggressive manner, and in addition there was this other crazy girl who would chase me around the schoolyard even though I didnt like girls at the time). The only things I could do was sit in my room and watch cartoons, or play videogames or draw. It was a life of total isolation.
From 14-15, I became more melancholic and having moved yet again I made a couple of friends but was generally still an outcast. I still liked to draw and play videogames, and got along great with other NFs, in addition to an INTJ who I was friends with. Though I liked to play a little bit, I mostly would draw in my art book, making things like mazes and anime drawings. I had the most fun with one of my friend's younger brothers and did some shoplifting, took up smoking and just in general became somewhat rebellious and disillusioned with authority (which I saw as oppressive). I wasnt popular and was called 'gay' and weird by the jocks, who were quite mean to me -- I hated junior HS terribly and since I took their criticisms personally this made me even more introverted and generally unhappy.
From 16-18, I moved back to my home area and went to this other school. I wasnt hated or mocked in a derisive fashion, any mocking was all in good fun and not mean spirited and I generally thrived during these years. I was still somewhat introverted and some people accused me of being snobby. I enjoyed learning a little bit more in this environment and it helped that I had an *NTP teacher who encouraged it and who I became pals with. In this environment I occassionally cracked off a bit of wit and became friendly with nearly all of the students (it was a very small school), including an ENFP girl who I enjoyed flirting with. I held parties at my house, and while occasionally kept to myself, still interacted with people.
Also, I am native american (mostly), and noticed that people at white schools were always much more vicious in their mockery. I did not enjoy any of my years going to white schools. I was always a little bit weird and abstracted, living primarily in my inner realm even whilst doing things in the outer one. It was just so fun for me, while the outer world seemed dull and boring by comparison.
