I grew up spending most of my summers on the water; specifically on boats. We’d go out on trips, toss the anchor in, swim all day and sleep under the stars at night.
On one of those occasions, I remember waking up to a sound that was rather odd. It wasn’t overly loud, it wasn’t mechanical, it wasn’t alarming..it was just different.
I laid still for a while listening to this sound, but finally got up to figure out exactly what I was hearing. When my eyes adjusted to the darkness I was shocked to discover we were in imminent danger. The anchor had slipped during the night and we were only yards away from hitting a huge rock formation that lined a section of the shore. The sound I heard were the waves as they gently splashed against this large, cragged wall creating an echo off the stern of our vessel.
Sometimes you get a warning..
an echo of sorts pinging in the dark.
But you have to be still to hear it.
