Pyewacket made a little song came to mind.

Halfway down the stairs is a stair where I sit
There isn’t any other stair quite like it
I’m not at the bottom, I’m not at the top
So this is the stair where I always stop
Halfway up the stairs isn’t up and isn’t down
It isn’t in the nursery, it isn’t in the town
And all sorts of funny thoughts they run through my head
It isn’t really anywhere, it’s somewhere else instead
Halfway down the stairs is a stair where I sit
There isn’t any other stair quite like it
I’m not at the bottom, I’m not at the top
So this is the stair where I always stop
