You don't happen to know what your personality types is, do you? It's just my normal way of quantifying these kinds of things. I'm an INTP.
Haha, I recognize this well =) I'm an INTJ. (And a Type 5 in the Enneagram.)

Do they just take it for granted? Is that why nobody talks about it?
Reading your comment, I'm guessing that must be it. I was really surprised I didn't get any comments (until yours) on this post or inspire others to make similar posts. I just can't imagine what it's like, taking this kind of thing for granted...and I can't believe little things like this still take me by surprise.

House was the first character ever where I was like, woah, wait, is this what it's like to actually identify with a character? [...] What did matter is that I instantly and instinctively understood him. His motivations and actions just made sense and were true in a way I had never seen on screen before.
Yes! House was like...glasses. And fandom discussions could be frustrating, because his thought process just seemed to freakin' obvious. God, and writing fic was a breeze, no over thinking it.

Never watched Bones, dropped Grey's before Erica showed up, never even heard of that last one, but I may very well have to seek all these characters out.
Kimi wa Pet was also made into 10-episode TV series, so you can check that out as an alternative to 14 volumes of manga. (Though it's been a while since I've seen the TV series, so I don't remember if it had the same nuance as the manga.)

I adore Amy, but the Who character I really identify with is River. I feel like she's a personal gift from Steven Moffat to me.
Reading the comments on the doctoreleven post, I think I view River the way Amy probably does: I want to BE her, but I'm not there yet.

People like me in fiction ARE NOT WOMEN. This starts to hurt after awhile. River is a goddamn miracle.
This!

I need to see this. Like, now...That scene sounds amazing.
It's in episode 605 "Invasion." I found that scene, and Erica's "glasses" one, to be the most moving in the entire series and among the most memorable in television.

Seriously, thank you so much for writing this. I feel better now.
Thank you for reading and commenting...I feel better, too.
