different names for the same thing

Alone on a train aimless in wonder.
An outdated map crumbled in my pocket.
But I didn't care where I was going,
Cos they're all different names for the same place.

The coast disappeared when the sea drowned the sun.
I've no words to share it with anyone.
The boundaries of language I quietly cursed,
And all the different names for the same thing.

There are different names for the same thing.
