I'm a live in caregiver, and I am due to inherit the family home and property. Others in my family have been told about this. My sister in law showed up and started cutting down trees that I had asked to have left for privacy. Parents are afraid of getting her mad, so they just go along with it to keep the peace. I feel like I am doing all the work around here but have no say so or respect as to my wishes. On one other occasion she cut down some flowers I had put out. She acts like she is the only one with any sense and constantly over steps boundaries. Any advice?
