On Hallowe'en (All Hallows' Eve), in Poland, believers were once taught to pray out loud as they walk through the forests in order that the souls of the dead might find comfort; in Spain, Christian priests in tiny villages toll their church bells in order to remind their congregants to remember the dead on All Hallows' Eve. In Ireland, and among immigrants in Canada, a custom includes the Christian practice of abstinence, keeping All Hallows' Eve as a meat-free day, and serving pancakes or colcannon instead. In Mexico children make an altar to invite the return of the spirits of dead children ("angelitos").
