I believed once that I could fix anything. That given enough time, or resources, or motivation, or help that I could honestly fix anything. It's the engineer's mantra, that given enough time and money any problem can be solved. It is an inherent optimism, a fundamental trust.
And on some level I still believe it to be true. But now II understand that not everything wants to be fixed, not the wino I tried to offer a meal in lieu of the $5 he tried to panhandle, not the mental patient that dumped the plate I'd fixed him one Thanksgiving.
