for example, not until driver's ed in 10th grade did i learn that this:
does not tell drivers that they are in the middleish part of california, where i in fact was, as i grew up there. (if you need such a broad landmark to tell you where you are, you probably should not be driving. however, this never occurred to me. i mean, look at california:. you can see the similarity in shape, can't you?)
another example happened just THIS YEAR. you know the phrase, "smooth move, ex-lax?" now, i always knew when you would USE this phrase, but only a few months ago did it dawn on me, the EXACT meaning of this phrase.i never had thought it was a particularly clever expression, but my curiosity went no further. now i know.
i know i have other examples of this. i actually find them really amusing. i don't always find it easy to laugh at myself, but in this case i can't help it, and i invite you all to laugh at me.
and in addition to marveling at what an idiot i can be, i will anticipate eagerly the next epiphany that everyone else in the world already knows.
