I'm not sure why I decided he lived in my closet and not, say, in the equally sinister under-bed region of my room. But rule the Empire from my closet he did, and sometimes I could actually hear his breathing when I was trying to get to sleep and trying to ignore the fact that my closet had a door, and that doors both concealed things and could be opened by things that were concealed. Things with black-gloved hands that could mime-strangle people and actually cause them to die from strangulation.
Probably inspired by my mother's "don't be scared of earwigs because they can crawl into your brain and befriend you" story, I dealt with my terrible fear of Closet Vader by deciding that spending so much time in my closet had led to his observing me a great deal and to his realizing that I was a well-meaning, thoughtful, and decent young person. He had been lurking in my room in order to kill me, but after getting to know me, he just couldn't do it. Did he therefore leave my closet in order to return to a far-flung galaxy? No. He decided to live in my closet forever more and to protect me from the other forces that menaced me (centipedes, mostly, and something else I'll reveal next week).
What I find somewhat discouraging about my budding imaginative powers is that, as far as I can remember, I used them to save only myself. I don't think I imagined a fully reformed, child-protecting, Rebel-Alliance-embracing Vader. He was still pretty much evil and nasty and rebellion-crushing—I just made him make an exception for me. If I had it all to do over again, I would absolutely speak up for Admiral Motti.
