I'm back home in Helsinki. What I ought to do is "juhannussiivot" (cleaning for the midsummer weekend). Well, I have been working in the garden. The day lilies are blooming, and so are the rose bushes.
My juhannussiivot is going to be something not so big, just normal weekly cleaning. But I quess many families in Finland clean really throughly for this holiday. It is the old tradition. Then after everything is very clean inside the house, you bring two young birches by your doorstep and put some summer flowers in a vase.
