My daughter was 16 in April. She has been invited to a party in a field in a large village on the outskirts of our town. It's about a 45 minute walk from home, starts at 8pm and ends at 1am. My problem is she doesn't really know where it is exactly and will be walking there and back. I was not totally comfortable with the walking home and the lateness. She is not willing to compromise and be picked up earlier because no one else is being collected and apparently all her friends are going and the parents are all ok with this. I feel that 1am is too late for a just 16 year old. Am I being unreasonable?
