Thank you very much @matkodurko ! In your words there is a grain of truth))) I loved to draw at school during lessons)) I did not just steal time, I spent it with pleasure.

But, my choice of tool, or material, is not related to boredom. I wanted to draw, and what was at hand was a ballpoint pen. One more thing. I do not make sketches and I try not to make mistakes. It does not always work, but it mobilizes me after a break of 30 years. I, later, will try my hand at watercolor.
