Oh my god, Little Matt, you have no idea how cool it is to see you back. I love this story - not just for the obvious things, but for the genuinely creative spin you've put on this trope. It's a whole universe with all these neat little gadgets and norms, and I just know that what fits into this story is just the tip of the iceberg of all the knowledge you've got in your head about it. The fact that you came back after all this time shows just how much effort goes into stories like these. I know I'm not alone in appreciating it. Thank you.

I'm a boy. That's just who I am, whether or not I have the right parts. Ken is still a man, even though his undies are empty, right? I just thought all girls secretly wanted to be boys, and felt their best when someone mistook them for one, right up until I said just that, and my family went "Uh, no." That's how much I took it for granted - that everyone felt this way, right? Because I'd never felt any different. I can remember when I started liking diapers, however. It was a set time, a set day, and then it just never went away after that. I was... Four, maybe? Five? One is a fetish, the other is my identity and my personality and my feeling of self. I didn't know I was trans before I knew I liked diapers, because I didn't even know I was trans. They're very much separate.

Sorry, but I can't help myself. History teacher here to tell you that Christmas trees are in fact much older, introduced into North American culture as early as the late 1700s, and very common by the early 19th century. There has, however, been an exchange of Christmas trees as a tradition in the 20th century following the war(s) which might be what you're thinking of. *ehem* Also, I really love this story. So well written, can't wait to read more.
