I were quite an asshole. I annoyed the hell outta everybody just to see how they react; Pick on them, stealing their things, sometimes even beating them up. On the other side, I always were a class-clown, and that's why I still got friends to hang out with. I didn't had many friends for a long time(only 2 best friends; though I "lost" them when I were something about 11; But I got new, anyway^^); Usually, I did much with one guy and after a half year I nearly did nothing with him anymore and found a new. In fact, I still have this attitude.
At school, I easily got through very good while doing nothing at all( The first time I learned was when I were 12 or so, and I still don't do much). The only difficulty for me was that I were accounted for EVERY CRAP about the teacher didn't knew WHO did it; Though I actually were it quite often.^^
In spare time, I played lego/cops and robbers with friends; Also, I read many books - even the bible partly - usually about topics that interested me, like astronomy or dinosaurs.
Lol, two things strike me: First, I nearly forgot everything about my childhood besides some general informations and some important points; Second, I don't really seem introverted. I'm constantly wondering whether I'm ENTP or INTP. Though, while I were getting older, I increasingly did more and more alone (and I got veeeeeery much nicer). Still, I have - and had - more than enough friends. I'm only unfortunate with the other gender.
Oh, I'm 18 now, so I am mainly talking about elementary school and early grammar school.
