«What’s wrong, Моm?» Jordie asked. I explained that when I was his age, my parents had taken my picture standing in exactly the same spot, and I was feeling rather nostalgic. I added that perhaps one day he would take his son’s picture here.

On this day, Russia celebrates the victory over Nazi Germany and honours 20 million Soviet people who died in the war. May 9 was chosen, since on the night of the 8th/9th of 1945, the Nazi Germany surrendered to the Soviet Union and the Allies in Berlin.

In Russia, almost every family has at least one person who took part in the war.

Older citizens who did not fight during the war worked in factories to make weapons, which was not easier than fighting. They, too, are honoured on Victory Day.
