Nothing lasts forever. But""especially as it seems to me cities and humans are symbiotically and inextricably bound at this point""I hope cities have a good, long run. Plus, cities are beautiful creatures in their own right; and as with us, their vulnerability and ephemerality are part of that beauty.
Make no mistake, your relationships are the heaviest components in your life. All those negotiations and arguments and secrets, the compromises. The slower we move the faster we die. Make no mistake, moving is living. Some animals were meant to carry each other. To live symbiotically over a lifetime. Star crossed lovers, monogamous swans. We are not swans. We are sharks.
