It was in the 80s of the last century. I lived in a student community. There was a Polish and Uzbek. They lived friendly. In the refrigerator there was a "country", that is, the whole barrel was common and was not divided into "my" and "foreign". So we got something new. A German postgraduate student from the DDR came to Moscow for an internship... We open the first day the refrigerator and smooth. The German bought the sacrifice and carefully marked it all with a black flommaster! In the door lies a feather of eggs and black crosses on all.))) In the evening the German opened the refrigerator and it was his turn to chew... On his eggs instead of crosses was painted a black swastika, and on our eggs colored red stars :)))
