Something I would have done 45 years ago: spy games. As in, I’ve got several bit metal items, used parts, screws, washers, nuts, extenders…
But in my imagination, spy gear.
Placed in inconspicuous spots, listening devices, imaginary.
Parallel fun at work, placing theses devices, monitoring. Will they be found?
We’ll see. That’s the fun. Setting them. That’s fun too. Moving them, also fun.
Making different devices from bits of metal. Goofy? Sure. Also FUN.
At work? In life? Have fun.

What can they be?

FUN.
