Yes, I did lie. In a moment of anger and frustration I said that I would kill my sister, however I did not actually do that. That was about the moment when I realized that actually she seriously was intending to kill me, and killing her would have definitively solved that problem, because appealing to mother to make her stop continuously harassing me never seemed to have any effective result, but then again, on second thought, why should I be the one to do the serious jail time.
