15 year old been lying and carrying on with an 18 Yr old. Asked not to until GCSE were over. Massive argument took her phone off her and she then runs away to Dad's who lives 200 miles away. Missed 1 GCSE. Is it bad that he can put up with her antics and the fact she believes she has rights?? Where my rights since I've the one who has bought her up for the last 5 years ?? My house, my rules??
