When I was a student, we had a principle in our dorm room - the last one washes the dishes.
But there was also a principle called "marine" - a sea wave will come and wash away all the dirt.
It was the end of the 80s, when there was nothing to eat in public canteens, and there were almost empty counters in stores. But these were the years of my youth and we were not worried about it. we were happy in our lives.
