"Dhalgren changed my brain," I say to Samuel R. Delany. I'm fanboying all over the place with this guy, and, to his credit, he's taking it in stride.
"Thanks," he says graciously as he signs my program, and I say a few more non-sensical things.
Finally, at a loss for anything to say in closing, I just blurt out, "Congratulations!" and scuttle back to the safety of my seat.
