If you want people to think you're insane and/or terminally weird (not that I can imagine why anybody would want that, unless you're Odysseus avoiding the draft), just try taking your writer's mind through graduate school, university faculty, and a couple of software development companies and trying to pass as normal. Try as I might to be careful, I kept having these conversations in which the other party would eventually stop and say, "You have a really interesting fantasy life, don't you?"
And it wasn't a compliment.
In the last such job I made an all-out effort to pass. No more obscure rock band T-shirts. Gray suit, check. Good shoes, check. Makeup, check. Toothpicks to prop my eyes open during meetings. Refrain from screaming when the tech writer rearranges your sentences to make them euphonious rather than true. All that and I still blew it.
I'd been taking the Visiting Professor to give his talks at two universities in the area. I had to drive him because he didn't like the car the company had rented for him. I forget what make it was, but he claimed that in his country only pimps drove that make of car. He kept making heavy-handed, unfunny jokes about this and calling it "The Pimpmobile." This got old quickly.
All I said, on the way back to Austin that night, was, "If you like, I can drop you off somewhere on East 11th and you can get an up-close look at some American pimpmobiles while you're trying to persuade a taxi to come down there for you."
Couple of days later I heard that one of my colleagues had asked him, "What did you think of Dr. Ball?" And he'd answered, "She's very intelligent, but kind of weird."
By contrast, once I came out of the closet as a science fiction & fantasy writer, the normal people around me relaxed considerably. Because now "weird" was just what they expected of me. I fit into a group they thought they understood and everybody was a lot happier.
Sometimes the road to "normal" is very, very crooked indeed.
