The beautiful mystery of engineering - where even engineers' kids have no idea what their parents actually do. Just disappears for 8 hours, mutters something about "tolerances" and "structural integrity," then comes home with a thousand-yard stare. Meanwhile, the rest of us are nodding along pretending we understand why bridges don't fall down. Engineering: the art of solving problems you didn't know existed in ways you can't comprehend. Next time someone asks what engineers do, just say "math stuff" and change the subject like the rest of us.
