An elderly woman dressed in all black is straddling the wrong side of a first-floor balcony. Standing up there with her is another elderly woman wearing a floral smock, bellowing unsolicited advice about how her friend should tie up the bunting. Fierce high-rise arguing descending into laughing, and I watch on in horror yet reassurance that, somehow, these ladies have got it handled. After all, it is quite possibly their 90th year of decorating the streets.
