When the people in high school that are used to getting A+ get a B-. They didn't really fail, they just need to say they failed to justify the B-. This technique also makes the kids who normally get B- and are totally okay with it feel like shit.
"Oh my god, I totally smart-kid failed. I only got a B- on my history final. Now my grade is only going to be an A!!"
"Jeez, I hate those fuckin' losers that complain about smart-kid failing, I'm just worried about not normal-kid failing!"
