We are quite conservative in Switzerland and I remember when my Swiss mother-in-law told me that hanging washing in public on Sunday was not really permitted. It was just not done, but this was 50-60 years ago and times changed. Today you hang out your washing on any day, dependent on the weather. Today is ideal, in the middle of a heat wave, it dries within an hour. My neighbour has already removed the washing line and probably put everything away. It does not bother me at all.
