Downstairs Upstairs

Up and down the stairwell,

Like a teddy bear;

One step, two step,

Tickle you under there!

 

The feet were dangling into the void of a stairwell, with a mirror facing upwards from the stairs beneath.

 

The same image was originally posted “upside down” in the linked image Upstairs Downstairs, but here it is in its “true” orientation. Then again, which way is up?
