Learned.

My brothers and I spent weeks with our grandparents by the sea where we learned so much more than it may have seemed. Not because we saw an actual shipwreck but because we saw the potential for it. Not because we actually found treasure but because we could feel the immanence of treasure at every seashore.  We fished for wishes and caught them; we swam to find mermaids and became them; and we dived for pearls and returned with a stick, a bit of litter, a coin or the makings of a joke. Pearls, in other words. We learned about tides and chance, storms and sun, the vicissitudes of what is lost and found, flotsam and jetsam, castaway luck, islands, sea-songs, rings, riddles and pledges.
