So I'm in Poland now (near Auschwitz), and damn I was in Seoul 3 months ago, it was 38°C (100°F), then I was in Portland for 2 months, also all the time between 35°C and 40°C, then I was for two weeks in Sweden, very nice 25°C (77°F), and now I am in Poland and again 38°C, this is the hottest summer of my life.
