DD is almost 12yo and she's just horrible :( We have all the usual preteen answering-back, stroppiness, door-slamming etc, and I expected all that but she just seems generally not a nice person and I'm starting to worry about it. She isn't actively horrible, she just isn't nice and doesn't seem to consider other people's feelings at all. She always thinks the worst of her younger brother and her favourite thing in the world is to correct him, put him down, show that she's better than him etc. It seems more to me that just 'normal' sibling rivalry. And with us she can be really nasty - she doesn't seem to be able to consider our feelings at all and when we explain, nicely and calmly, to her that she is upsetting us she genuinely can't see that she's wrong. It's not just with family, either - there have been a few instances where a friend of hers has had a problem and when I've later asked DD how the friend is she shrugs "dunno... haven't asked...". Do you think this could just be preteen stuff and that she might come out ok the other side - or is this just her? :( We can talk to her, discipline, reward and so on but I am worried that the basic kindness and caring that should come naturally to a human isn't there with her.
