 I would actually say it's the other way around. Those of us who've studied academically, even those of us who stand on stages and speak, can still find the one-to-one conversations hard. So I find it much easier to stand at the front of a room full of atheists when I do an event on a university campus because, in a sense, I've got a context. I find it harder to talk to my next-door neighbor and have that natural conversation. That takes time and energy, and it's tough, and it's the same toughness for me as it is for anybody, whether they've got a PhD or not.
