For all the wonderful things he says about Doyle, and the respect he shows for his work, I don't think Raul would flake out on him without a really, really good excuse.
That's what I'd like to think, anyway. Whatever it was, it's unknown, and I suppose it's so because it's none of our business. But, being that I doubt he'd back out on someone like Doyle unless absolutely necessary, I hope he's okay, and all that.
It was kind of ironic, really. I was disappointed, obviously, but I learned so, so much from hearing Doyle speak that it just didn't matter all that much that Raul wasn't there. He would've added a lot to it, but I didn't feel jipped by the lack of his presence.
Doyle's a genius. Seriously.
A work of art is an invitation to love.
