I sometimes feel like I'm building a sand castle. I mold the sand with my hands and my shovel, slowly and painstakingly smoothing harsh edges and firming up weak spots. I work on the moat, construct the keep, and space the cylindrical flanking towers at even intervals to attack any crabs or dogs that may try to storm my construction. Then I use my putty knife to carefully carve a castle gate. Finally, I put a stick into the keep and imagine a little flag hanging from it. I step back and admire my new castle, proud and content and excited for its future.
Then a wave comes and smashes the fuck out of my castle. It washes away while I stand there, helpless.
I sigh, and begin building anew.
