On the Sunday before Easter, there is a tradition here in Finland. Children dress up as witches and knock on doors to sing a song: 'Virvon, varvon, tuoreeks terveeks, tulevaks vuodeks; vitsa sulle, palkka mulle'. It means they have a twig they'll wave to wish you health - in exchange for payment. They wave these twigs (decorated with with feathers and stuff) and give them to adults in exchange for sweets. Jaava is waiting for them to visit.
