My very well behaved 15 year old wants to go out with his mates at 3am. He’s a good kid, polite helpful, easy going very reasonable he knows right from wrong. I’m not comfortable with it at all. I’ve not met his mates I believe 3 of them will be going. Apparently they will be walking round and stuff! We live semi rural town im not saying completely safe as things do happen. Am I being unreasonable to say no? Help!
