Heh! I love all the characters so much more the way you describe them--the weepy virgin, blithering eratomaniac and inexplicably changed (though it's not visible to the naked eye) idiot. Though I don't think her people really change, it's just if it's good love (with a Gryffindor) it shows you the good person you really are, while the bad love might make you stray from the path before you throw it off like Dumbledore. Or something. But yeah, it does seem like however it happens, it's going to be based on the author's experience.
