hm. Sounds like part Aspie stuff, part subconscious defense mechanism. I know that sometimes when major things happened (i.e. when I was sexually assaulted) I've just shrugged and made myself believe it wasn't that big a deal. Sort of like if I didn't react to it, it wouldn't bother.

I guess I was sort of right, except that I ended up with 9-13+ different personalities because of doing that. O_o I don't think it works quite the same way with death, but maybe somewhere along the way you've learned that things run more smoothly if you don't try to make yourself feel sad/upset over it? I dunno, just a theory.
