My cousin's half sister has just asked via facebook if she can borrow £20 ASAP otherwise she will have to prostitute herself to a 51 year old man. She has told me not to say anything and I don't know what to do. Firstly do I lend her the money, secondly do I believe she is telling the truth, thirdly do I tell anyone because if she is telling the truth and this has become a possibility for her both her and her DD are at risk. Not sure if it is relevant but I should add that I very rarely speak to her and her sister due to us both growing up in the middle of a family arguement. It sounds bad but I hardly know them TBH.
