On my way back, gazing skyward to admire some of the buildings, I heard an urgent "pardon, mademoiselle". Delighted at the "mademoiselle" bit, rather than madame – well, people have been saying I look years younger since I retired - I stopped abruptly, just in time to avoid a huge pile of something I did not want to step in. After thanking the men for the warning, I kept my eyes on the ground on the way back to the hotel.
