I never felt any social pressure except among my age-group.

GT kids get singled out early on by bullies.

When I got to a new school, I got picked on and called a sissy because I carried books around all the time, spent time talking to adults, spent time observing stuff, etc. That got corrected on the soccer and football fields when I deliberately repaid people in kind.

I knew one girl who was a NMF two years before me in HS whose tormentors began picking on her when she was in 2d grade and it continued into HS where the coaches put a stop to it. But it left huge scars.

In another school, there were two kids who were later NMF. One played sports and was never picked on. The other did not and was often slammed into lockers, etc. The latter told me it had been going on since Middle School.
