Stanley Joseph, the groom, who works as a driver for an NGO, tries to remove bride Daphne Gerard's garter from underneath her dress, as their bridesmaids look on, during a wedding game, after getting married in Port-au-Prince, Haiti, February 14, 2019. Gerard wondered if they should postpone their big day when it became clear a majority of their guests would not make it, due to the violent unrest that had gripped Port-au-Prince for months. Joseph felt they could make it work, although that meant chartering a plane to bring Gerard's parents up from the country's south-east. "We always have problems in Haiti. You can't wait. You just have to get on and overcome them," said Joseph. "I was stressed but happy." REUTERS/Valerie Baeriswyl SEARCH "HAITIAN WEDDINGS BAERISWYL" FOR THIS STORY.
