Harlan Ellison tells people who ask him where he gets his ideas from that there’s a company in Schenectady, NY, that sends him a six-pack of the things for $25 a week. I’ve always loved that answer because it reveals the ignorance of the questioner and allows the answerer the opportunity to pontificate.
And, being honest, a lot of writers like to talk. It’s part of why we’re writers: we have something to say.
