No one builds a life, we survive for a time in that sea by swimming through currents where random pieces of flotsam and jetsam keep us afloat for a time then sink, or move on, leaving us to swim again, looking for land that does not exist in the form we seek.
For moments settle on islands until they no longer sustain us or the sea rises up and washes us out into the currents swimming to survive, but in the end we cannot.
The best we have of the sea are memories of what we hoped for and the dreams we dream when we sink below the waves to sleep.
