For me, the sea has always been a confidant, a friend absorbing all it is told and never revealing  those secrets; always giving the best advice — its meaningful noises can be interpreted any way you choose. For Alberto, it is a new, strangely perturbing sight, and the intensity with which his eyes follow every  wave building, swelling, and then dying on the beach,  reflects his amazement.
