I remember one clear SJ in my high school who pretty much ran the school. He was very mature for his age, wore a shirt and dress slacks every day even though we had no dress code, and was president of the honor society. He was chummy with the principal and the higher-ups and patrolled the hallways putting the underclassmen in line. He hated any kind of disruption or tomfoolery. Wasn't a particularly fun guy.
Ha, this is such a stereotype but it was true. He was an extreme ESTJ, though.
I hated being an SJ teen because I was so much more serious than everyone else, and I couldn't stand the SP fun. I'd be the first one to tell on someone cheating during a test. I was a goody-goody.
SPs think you're a bore, and the NTs and NFs only tolerate you because you work well (SJ band leader/newspaper editor/art club secretary etc). I was very focused on doing well in school and getting good grades. Of course, I didn't fit in.
Don't SP's pretty much dominate high school social scenes? I'm sure they're responsible for lots of high school misery. They drive fashion trends and what's cool to wear, what kind of stuff you should have in your locker.
