Interesting article about the BBC Nativity I keep going on about. 'People will be talking about this' say many Christian commentators, so worth being ready to listen to what they have to say.
And it goes without saying, please don't be in too much of a rush to tell others your interpretation but listen long and hard. Then maybe invite the interested questioners to something to follow it up. If there isn't anything you can invite them to, pester your minister. If you have no minister do it yourself.
