What should I do - our daughter is making accusations of physical abuse against her brother to a therapist, although we know they are not true. She is in her twenties now and being very hurtful. Over the years we have experienced all sorts of lies from her, but I feel this could become really difficult and I don't know if I should ignore her or confront her. We haven't told our son incase he gets really worried unnecessarily. I would really welcome some advice xx
