‘Plichtpleeghing I’ (Painting 23)

For the sake of nostalgia I decided to re-watch a few episodes of a show I was fond of in my teens. Somehow I ended up watching all 300+ episodes (again) and came across a specific part that had left an impression all those years ago, but I had utterly forgotten.
It’s a small bit of poetry that is specific enough that I could mold it into something of my own. It instantly gave my ideas for a series of paintings, this one being the first.

Keeping some details vague on purpose as I’ve got a little challenge going on with a few friends to see if anyone can guess the correct reference, but I also don’t want the show (and reference, should I mention it) ruin the interpretation that might else be lost.
