Host
I'm Charlie. I'm not a historian, and I'd rather not pretend otherwise. I'm someone who falls down a rabbit hole on a Tuesday and by Friday has to tell somebody about it.
Mostly I host on my own, which means I do the telling and the heckling, occasionally in the same sentence. Every so often a mate comes in to take over the yarn and I get to be the one asking the dumb questions instead. Those ones are flagged so you know what you're in for.
