Need some advice my grandson is 16 and has high functioning autism. He has a part time job in my daughters office in London. Occasionally her and his step dad allow him to drink alcohol ( I'm not happy about this) Yesterday she let him go out with work colleagues without her and he had to get home alone on the train. I'm scared for him do I say something? My daughter and I have a fractious relationship. What's more baffling is that they are both recovering addicts and obviously don't drink!
