When I used to go to the doctor's office there was a shelf of toys in the waiting room. Every time I went there I would pick up the toys and put them all on the shelves. I would go so far as to take toys out of the hands of children who were playing with them to organize them on the shelf.
When I was in the 4th grade, the principal screwed our class out of a field trip. Every class before us had gotten the field trip, but she shifted it to the grade below us our year, so we missed out. I wrote up a petition for our class to get a field trip too, and had the entire 4th grade sign it. The principal was actually very pissed off about it and called my mother in for a meeting. She harassed my mother and scolded her for "making me" write the petition. My mom was like, "What petition.....?" because I hadn't told her about it. And then my ENTJ mother proceeded to inform the principal that a 9-year-old just handled the situation in a more adult manner than most adults would.
As far as my introversion... Whenever kids would call me to hang out I would tell my mom to answer the phone and tell them Im not home. If she made me talk to them I would always say, "I'm grounded Im not allowed to come out today." My mom used to get so pissed and was like, "Everyone is going to think Im the bitchiest parent in town! They think you're always grounded!" I don't think I ever actually got grounded in my life.
However, I apparently had this death glare. My aunt started refusing to babysit me because anytime she would try to tell me "no" about something, I would just freeze and glare at her without blinking until she gave me what I wanted.
I also had a teacher in the 3rd grade who had me transferred out of her class because she couldn't "punish" me. I was getting really bored with school in that class, because I would finish assignments way before the other students... So I would end up getting disruptive sometimes because I had nothing to do. She would SCREAM at me, and when she screamed, a little vein in her forehead would pop out and it made me laugh. So I would always end up laughing at her when she yelled at me. She tried keeping me inside over recess, but I didn't actually like recess so I never cared. So she tried sitting me in a corner facing a wall. I would sing/hum and sit there happy as a clam just to spite her. She actually got in very serious trouble because she left me in a corner for 3 hours one time, because I wouldn't stop smiling and humming. When I told my mom about it she was furious and went to the school board.
After that I pretty much ended up going to my classroom in the morning, picking up my assignments for the day, and then walking to the 'gifted education' room, where I spent the remainder of the day working on things that my gifted education teacher came up with. I was kept out of that teacher's room, and when I got older I found out that she actually claimed to the school board (in defense of her leaving me in the corner for 3 hours) that I was giving her anxiety attacks and she was seeing a therapist. I consider it a victory.
