A child reacts to a reveller dressed as a devil at the Old Town Square in Prague, on the eve of Saint Nicholas Day December 5, 2013. Revellers dressed as Saint Nicholas and a devil approached children on the streets as part of a tradition to determine if they had behaved well during the past year and depending on their answers, would receive presents, sweets or coal accordingly.
