Good one, and you now have a mantled wall!

These are called orphaned negatives and English has loads of them. A great article about them is here: https://stephenliddell.co.uk/2021/03/17/a-gruntled-look-at-orphan-negatives/

I'm intrigued. What question did you answer?

This is brilliant!

You can cut a tree down and then cut that same tree up
