ETA: I'm not condoning kirten's behaviour. She needs to pull her head in and control her frustration and find a better way to deal with her issues. But she hasn't had a disciplinarian in her mother and so she doesn't know any better! But she needs to learn I agree.
I wish more parents would look at their own faults when their children show unsavoury behaviour patterns. It's always 'the kid is a brat' yada yada but the parents play a major role in that! I know I look at my own actions/behaviour when DS acts out.
