The photo of the man with the vacuum cleaner was taken in Cannaregio, a sestiere (district) of Venice, at the beginning of Carnevale in 2014.
I, along with a throng of other onlookers, was waiting on the other side of the Cannaregio Canal to watch the parade of oar powered boats arriving to mark the opening weekend of the festivities. The dramatic finale of the parade was a larger than life pantegana (rat) whose rear end exploded, releasing a swarm of coloured balloons!
Later, we had the chance to try many typical Venetian foods and beverages from stalls set up on the fondamenta (canal side walkway), and listen to Venetian musical presentations. It was cold, but a lot of fun.
This couple were on an adjacent balcony. Their housework must have been done, so they could enjoy the passing parade.
