The struggles of being too smart

First off, my education is limited. I only know the basics of aristocratic conversation. I think I've put in a lot of effort to master it through self-study... especially since I was poor... I don't know difficult Chinese characters or idioms either... Honestly, being smart doesn't mean being intelligent... It doesn't mean I was studying Pythagoras' theorem in my mother's womb... It's just that learning is easier and faster for me than for others, that's really all there is to it... But, sometimes... people use difficult words with me, assuming I'll understand, and it's really bothersome... What's worse is that they genuinely believed I would understand, not that they were trying to trick me... If I haven't learned something, I don't know it... really, anything... There's no way I'd know about the power struggles between middle-class or quasi-conglomerate families... My IQ, according to Wechsler, is just a percentile among my peers... so the higher the number, the fewer the comparison group, which makes it really meaningless... My mind is like a vast, empty mansion warehouse... I wish people wouldn't assume I know everything.
