The afternoon sky is a clear baby blue and a happy sun shines down on the denizens of the neighbourhood. I am walking with a brisk step in the rather chilly April air. Residential houses and small restaurants flow passed me as I walk. Even though the fine weather is making me cheerful it is all the same as yesterday and the day before and every other day. Only one thing is worthy of note: all the people sitting at tables out on the curb; just because this is one of the first really sunny spring days. It’s a phenomenon in northern countries, as soon as there is a hint of sun and warmth people move out to sit in the sun even if they need wear an extra jacket.
