At least here, and why not worldwide, everbody has been asked to light a candle and put it in his window as a sign of thought and solidarity to the victims of the earthquake in south-east Asia.
I am aware, they will not see it, and it won't help them, but what would this world be without a bit of humanity and how dark would our lives be if not someone lit candles in the night for us sometimes?
So, if you think of it, do it.
