Tiny shadow - Entry for the Shadow Contest/SMASh

For days I have been thinking about the next shadow hunters contest and what I wrote in one of the previous posts (when I posted the shadow of a large object...). The next shadow will be small...
And then I think for days, what to photo... How small object should be that makes a small shadow...
And while I was in the office all day today, with my mind on some financial reports, the sun shone on the side of the building where my office windows are. Fortunately, the curtains were down, so the sun didn't bother me much. At one moment I looked at the curtains and noticed exactly what I needed. At first I wasn't sure if it was a shadow or a stain... When I got closer, I saw that it was a shadow, and a very small one, the shadow of a bug.
Extra.
I have a picture for this week :-)

As an addition, I insert one more picture, proof of the lack of culture of my neighbors who write graffiti on buildings...

@melinda010100 I think this graffiti is totally in line with this community :-)
