Well, I remember asking for that... I thought having a manual with pictures would attract my son and his friends, but alas... as they said in one Russian cartoon, "Like father, like son... not."
But still, thank you very much for the aforementioned manual; this year, during my vacation, I plan to work on this... last year, COVID-19 affected me greatly, both in terms of work, with my laptop crashing and losing many of my developments, and in terms of health... from November 14, 2020, to December 28, 2020, I was very ill, as I have chronic bronchitis, but praise be to God, I recovered and am slowly finding the strength for my hobby!
Regarding your son: everyone has their own interests and hobbies. Regarding the pandemic: yes, it was a difficult year. It hit me hard, as it did many others. I'm glad you recovered. We'll get through this; everything will be alright.
