+So I take a break, wander down to the park to stand, then lean into
+the concrete railing demarking the beginnings of space, oceanic
+space. I watch the waves break, and form, and ease back out to sea and
+wrap my arms around myself and hug tightly because it's early in the
+morning and windy, and the sun is late getting out of bed today, which
+is good because if there was brilliant light illuminating all the
+beauty around me I would be shocked, stunned, forced to retreat back
+into my cabana in a daze, blinded by hummingbirds and callilillies and
+un-named red, yellow, and blue flowers. Green envelopes me, waves
+sooth me. I can see the wind flip the top of the waves seaward, right
+before they break. The sea seems so calm from my perch above the fray
+that I wonder if maybe there is just some part of the deepest, most
+abstract ocean where there is a large creature who happily chews
+plankton and wags its tail in gentle, adulating waves that spread and
+move and gracefully glide thousands of miles, to crash upon a beach,
+one after the other, politely waiting for a turn to dance with the
+seashore.
+
+I know: it is what the Mexican schoolchildren call "la vibora de la
+mer," the serpent of the sea.
