I’ve collaborated on a story with someone I think twice in my life, the last time maybe 15 years ago. And I miss it. I found it creatively fun. But I’m not the sort of person who can collaborate with just anyone, and certainly not with a stranger; it’s too personal an experience for that. I’m probably just odd that way. And I’m sure some writing styles would clash too much to collaborate to create a seamless story. But I do miss it.
