As Jared said, another three or so hours yet here. But since my family are Polish, we celebrate on Christmas Eve anyway since that's what we do. So we have a Polish Christmas on the 24th and an English Christmas on the 25th! Double the Christmas :)
Traditionally, the meal begins just after the first star appears in the sky. The youngest child is to stand outside and wait for it - then to rush inside as soon as he or she spots it so the meal may begin!
Quite incredibly though, we saw on the news that the International Space Station was to make a very close pass to the UK this evening in just such a way as to be exceptionally bright. So at 17:22 on the dot we were stood outside as a family and watched together our little shooting star pass overhead this beautifully crisp and clear night as the start of our Christmas. It's quite incredible really to think that 2000 years on, we're now able to put our own stars into the sky. It was a very special moment, and one I suspect will not come around a second time.
