I've been RPing characters with long, mobile ears for so long, I feel like my RL ears are the same.
It's the strangest, craziest thing. This morning I was remembering something embarrassing I did when I was younger, and I swear that I felt my ears pressing back against my head in embarrassment. Not my little people-ears, it felt like I had long ones and they were pressing back. Then I thought to myself 'Wait, I don't have long ears!' and the feeling faded somewhat (didn't totally vanish though).
I wonder if it's related to the phantom limb phenomenon? I've been RPing elves a while now (more than a year), but not anywhere near as intensely as I used to RP (sometimes I even go a whole day without any RP at all!). It's kind of sad, my new state of RPing*. I remember how cool (and scary!) it was to have a character's voice in your head all the time, being able to see the real world through their eyes, hear their opinions on things, I miss that. (Though I do feel a lot more sane with only one voice in my head!)
(* Edit: This is not a passive-aggressive comment at anyone, it is not a hint that anyone is not RPing with me enough, or that I'm unhappy with anyone. The amount of RP a person gets is a direct result of that person's effort to get RP. :) )
