A Penny for Your Thoughts, Redux

Two days in a row I walked by a penny on the sidewalk. I did not pick it up. Time was, out of a sense of good sense (and cents) and savings, one would pick up a penny, even if for good luck. I did not bother. This disappoints me. Not that I harbor sentimental illusions about how much I am missing out on, how much my savings potential is diminished. (On that note, I am diligent. I have a large change jar, sometimes two. The resultant savings have paid for trips. I have also started a savings envelope, to which I contribute sometimes more than once a day: for fun and emergencies. I highly recommend these pecuniary practices.) Would I stoop to retrieve a dollar bill? Yes. But my inaction reflects a mindset, a way of thinking that got us into this economic morass. Many would pass up a dollar, I'd wager (though wagering is against the spirit of saving). Would they sneeze at a five or a ten? Walking on the sidewalk, when I was in first grade or so, I found a five-dollar bill, on the grass, moored there waiting for me on a windy day, if memory serves. What a thrill! What would that translate to in today's dollars, or euros? There are unwritten conventions, or used to be, regarding such findings. If you are in a hallway of a building and you find, say, a benjamin, are you honor-bound to inquire if anyone has lost one? Is that naive? What do you do next: invite claimants to recite the serial number? Funny thing is, I don't know if the penny is still there, waiting. Maybe it's a 1909 S VDB penny.
