My 17-year-old daughter is working full time. Last year she was in college and I spent a lot of time supporting her, but she really struggled. I agreed with her decision to leave college but I told her my expectation was she would find a job and pay us some rent. At the time she agreed. I would like her to pay £100 a month. She is refusing. My mum thinks I'm wrong to ask her for rent. A couple of good friends think my expectation is fine. My daughter does very little around the house. Am I reasonable to expect this or not?
