Summary
One day a man stumbles upon a weird looking creature in the beach which was later preferred as the "lost thing". Later the man was looking for the place where the lost thing belonged. At the end they found a place where there were many like the lost thing.
What is thing?
I believe the thing is like our imagination, back when I was I child, if I’m lost or if there is nothing in mind. I like d to imagine weird things in my head. I think it is something similar to it.
What I thought
I think the story is telling us about our imagination. When we were younger, we used to imagine many things, when bored, lonely or other occasions. But after we grew older we stop imagining much any more.
