I know tomorrow is St. Jerome’s Day, and I know Monday was European Languages Day, but I only accidentally found out that this week is the Woche der ausländischen Mitbürger (Week of Foreign Fellow-Citizens).
According to the poster, these are Giovanni, Ulla, Alexis, Dimitri, Paolo, Petro, Ümüt and Mei Ling, and most of them live in the top storeys (perhaps there are no Hinterhofgebäude where the poster was made).
There is something in Erlangen called ‘Ich muss etwas von dem Eigenen in mir bewahren um dem unbekannten Anderen gegenüber offen zu sein’, with no further details. Nothing else local. But I think there’s more on the programme than for the European Day of Languages.
