I'm 19 and have a 16-year-old sister. When I was laying on my bed minding my own business, my sister, who was still angry over something, came over and bit my hand. Like really bit my hand, which left teeth marks.
I am at my wits' end! I can't figure out what I should do about the biting. I've looked online for help but no one seems to be having this problem. She has been known to bite me when she's angry, but then she tries to manipulate me into thinking her biting is okay and I'm the one to blame because I'm older. I can't do anything, to make her understand. I'm the eldest and she the "baby" so my parents won't get involved.
Please give me some advice.
