For me, it's always been easier to write a character or pairing that I don't really understand. I know that sounds crazy, but I always work harder when I'm writing one unfamiliar to me. I guess because I feel like I have to..."earn" that pairing more. Like I have to dig deeper into them than I do one I ship because when I ship what I'm writing, I'm like, "Okay. So this happened. The end," because I subconciously assume that everyone has the same interpretation of canon that I do because it's "omg so obvious."

I do this in every fandom. Even back when I wrote HP, I hated Harry/Draco, but I've got 8 H/D fics, and they're better in quality than the ones I wrote of my own OTPs. And in a few cases, there are more of them, even.

It's just a weird thing I do. Spike/Buffy? Couldn't write it. Warren/Andrew? Obviously can't. Now, if you asked me to write Bangel? That I could probably do.

I'm a very weird person. I accept this.
