Reverse writing

[Empty_of_Clouds]

Is it really a thing?

In all the time I've used fountain pens, both recent years and distant years, I have never felt the need nor desire to write with the (often untipped) up-side of the nib.

So, do people really reverse write with their pens? Or is it some weird thing that has been born on YouTube?

Colour me curious.


ps, asked around and nobody I personally know has ever heard of it.
