DD age 12 (school year 8) has been invited to stay the weekend with her best friend from primary school who has moved to a town 2 hours away by train. It is a straight journey by train with no changes. I would put her on the train at Euston and the friend's mother would meet her at the other end and put her on the train to go home. DD is happy to make the journey by herself. DH got very angry when I told him of this plan and said he didn't want her to on the train by herself in case "something happened to her". We had a massive row about it. Is he being unreasonable or am I?
