Some stupid crap I wrote in my notebook half a year ago

Everybody knows walnuts. But do we really know walnuts? I think it's far more accurate to say we know the concept of walnuts. If you ask me if I know what a walnut is, I'll of course say "yes." But if you ask me to state any sort of facts about walnuts, I'll pretty much draw a blank. Sure, I could tell you the basics -- they're nuts, they grow on walls -- but outside of that I can't name one aspect of the walnut I know by heart.

My point's obviously a broader one: walnuts need to be taught better in schools.
