Actually, recently he became a bit more active, and we are even playing with the idea to form a duo 😎
It is just that we both are too busy during the week ( as I work and he has school + conservatory (here they call that the music school), + extra maths, physics, chemistry lessons) we almost never see each other - just for lunch /dinner and evening. We would need some time to practice together but he is sightreading very well, me too, so in a day we can easily put together a repertoire.

Well, I think I put on private the video from the post, as he doesn't really want to appear in public right now :D

again, tricky age 😅
