As the Litany of the Saints reverberated down Rúa do Franco, I couldn’t have felt more self-conscious. It sounded like there was some latter-day Crusader army behind me due to the acoustic effect caused by the narrow alley’s granite walls magnifying the voices behind me. We were getting a lot of attention. Heads were turning, people were rushing out of shops and restaurants to watch, with mobile phones being whipped out to take photos and videos. There would be footage of me being a Catholic and professing my faith. It was deeply unsettling. What might my friends say.
