"I'm not sure there's a definition that isn't circular. Relevant is relevant if I feel like it's relevant at the time. I'm not a hundred percent consistent about it, so the results aren't a hundred percent consistent either. But, say, I don't have to be granting a prayer as long as I'm responding to it - the apple tree of no was still a response, and I can get way bigger than the original scope as long as I'm still basically on topic - like I did with shrens and hearers and dementia."
