In the end only kindness matters...

I had a challenge once in my life: to learn how to use this evil device "счёты". I managed it and I think it was once from the biggest achievements of my life ))) By the way: we used to compete with real masters and old fashioned bookkeepers with those almost always won against modern electronic calculators. It was a lot of fun. But the bookkeeper's children used them for a ride, even better use.
