Step by step

Thanks for fave, buonacoppi!

Je te remercie le fave, Françoise Legeard!

Each step composed of tread and riser. The tread is the part stepped on. The depth of the step is also the riser. We tread on the tread of each step. We are the steps we look at here. You are the steps. We rise, gently we rise together.

It's exactly that, Steve. In such a structure we don't go upstairs, we walk upwards!
