My grown-up self could have written (backwards of course) what the wonderful Alison Bechdel of the indispensable lesbian comic strip Dykes to Watch Out For writes about herself as a kid:
I began carrying a pocket knife, begged to have my hair cut short, took up spitting. I had no illusion that I was a boy, though I liked being mistaken for one. But it was just as clear to me that I wasn’t really a “girl.” Oh, I continued using the girls’ bathroom and checked the female box on questionnaires. But in my head I occupied my own private Switzerland, where I spent the remainder of my childhood in splendid neutrality.
