I'm an atheist with pagan sympathies and DS and I have a kind of general ongoing 'story' that we tell each other, on the theme of DS goes and has tea with The Witch and they have some sort of Adventure. When I started doing it with him I was just rambling in the general 'tell me a story' way, and then we got on to there being a Witch and I just started adding stuff about the friendly witch tells him about herbs and the turning of the seasons etc... but I am running out of ideas, so any recommendations?
