Went to the Yiddish class today.
Surprisingly enough, yesterday's mysterious stranger wasn't there.
Even more surprisingly, the class was taught by a Dutch guy I sort of knew. Who addressed me in Russian. Very good Russian, too. I'd never heard that he knew any Russian before now.
My absurdity meter went through the roof, and I had a feeling that the logical conclusion for the evening would be for the Dutch guy and myself to mix vodka and beer, drink the resulting cocktail in the bushes next to the parliament building, and sing "Heveinu Shalom Aleichem" in Icelandic, thereby killing all the seagulls within the hearing range, but I did not quite have the heart to suggest this. Maybe next time.
I did learn quite a lot of Swedish, though.
