The most important holidays are Christmas and Easter. These are very spectacular. At such times they change the clothes of the homes. The day of Lucia is quite important to the Calvinist Swedish. In Sweden, people can let off fireworks, because it is legal there.
Child welfare is a substantial thing in Sweden.
The local governments have a person who revises the social standing of the children, and if there are serious problems in a family, they immediately take steps. They visit the family and try to help. The laws strictly punish abusing children. It was hard to endure the long, frosty and raw winter, that typical feature of Scandinavia. Where I was, there was not much snow, but I enjoyed the cold that penetrated into my bone.
