A discussion started at work about when to take down the Xmas decorations. In all my years I'd never actually taken the time to find out what 12th night is all about, OK, maybe I went to see Shakespeare's 12th night on 12th night in Stratford but that was a lot of years ago
Anyway, a bit of googling and it turns out to be nothing to do with religion and everything to do with tree-spirits.
And twelfth night is Jan 5th, the eve of the 12th night so get those decorations down or you will annoy the tree-spirits
