Coinage
"When you were a kid, do you remember when you dropped a coin that rolled under the table how you didn't even think about what to do... you simply threw yourself to the ground and went crawling after your money? It didn't matter if it was just a nickel or even a penny, you chased after that shit.
And now, as you grow older, do you notice how the value of the dropped coin you're willing to chase after keeps getting bigger and bigger? At one point you stopped crawling after pennies because, after all, it was just a penny. Soon after, nickels weren't worth bending over for. In no time at all, dimes are more trouble than they're worth. With age comes the realization that the time, effort, and energy required to retrieve dropped money requires careful calculation. Is the quarter that just fell out of your pocket worth the risk of straining your back while bending over to pick it up? What can you get with a quarter now-a-days anyway?
Today I dropped a dollar bill while pulling my iPod out of my pocket. As I stood there watching my money gently tumbling down the sidewalk in the breeze, it then occurred to me that I must be an old man now because I had no desire to go after it. Then suddenly, in a desperate bid to reclaim my childhood, I went chasing after my dollar. Just as I bent over to pick it up, my $180 Oakley sunglasses (one of those ridiculously expensive purchases you try not to regret) fell out of my jacket pocket and got a nice scratch on the lens. Standing there with a dollar in one hand and my ruined sunglasses in the other, I threw the dollar bill into the air and walked away having learned a valuable lesson.
