This seriously concerns me.
I spent at least a year- a year!- watching Avatar- Avatar!- without giving much more of a thought to who'd get together than "oh, yeah, Aang likes Katara, I guess." Even once I'd heard of shipping- nadda. I didn't care. Just liked to watch the fandom. (I sort of ship Tokka now. But that came later.)
And, in my young, foolish days, back when I read Twilight in all seriousness, Bella and Edward made me squee. In all honesty, they still do. I CANNOT HELP IT. I HAVE TRIED. DO NOT JUDGE ME.
I finally acknoledged that maybe, maybe, I might ship just the tiniest bit when I started scouring the internet for Han/Leia. But that's not shipping-shipping! It was resolved ten years before I was born! That's just liking the dynamic between a canon pair!
Still, I admitted that they were my OTP. My only OTP. That was as far as shipping went with me.
It took me months further to realize that I now watched and read things with one eye who "who got together" instead of on the action. That occasionally, I even was disapointed when the main character chose someone else.
I try to get into comics, and what am I reading? No, not action stuff. Batman/Catwoman fluff. Because that's my favorite type of fanfiction. PG to PG-13 fluff.
Lord help me, now I'm trying to write it.
I can't write romance. I cut my teeth on Twilight- I cannot write normal romance. I spent a several month period killing off almost every love interest any of my non fanfic characters had. Seriously. One survived intact, and he barely did. Now I've got to de-Wangst them!
And I'm a shipper.
For the last five months or so, I've been introducing Avatar to my Aunt Mary. She's really liking it, much more than she expected.
And within four episodes she was a Zutara shipper.
I really do not understand how this works.
