As a child I remember my Mum or Mummy as we called her,watching the sky after a rainstorm, looking for signs of sunshine. When we would say we saw a patch of blue sky she would ask, "Is it big enough to make a pair of trousers for a Dutchman?" (referring to the full, traditional Dutch/Hans Brinker trousers of days-gone-by).

I often think of that when I see a sky like this.....
