The shit part about being "the strong one" is that you're not necessarily strong because you actually are; you're strong because other people need you to be.
What happens when the rock that has been holding back the waves disappears?
The villagers have to fight the waves themselves.
Everyone wonders where the waves came from, some people remember the rock but
asks how the rock feels, having been crashed against, worn down, and finally toppled.
But all that's left is rubble anyway. Not that you can see it; the sea claimed its property.
