I should've known that!

I often feel stupid for not knowing how stuff works before I'm taught how stuff works. Perhaps from once too many paraphrases of "You mean you don't already know??? Hahahaha what a loser! GRTFM." Unfortunately condescension hides the fact that lack of experience and knowledge do not beget a lack of intelligence. But what's worse is that sometimes even maturity cannot outpace stigmatization. So learn it young: just because you don't know something doesn't make you stupid (or an idiot), although it can reveal or even evoke shallow or obtuse behaviors from others.
