Having a dispute with 15 year old DD (year 11) about what is an ok time to be out on a non-school evening. We live in a small, touristy city which is generally pretty safe but with a lot of stag/hen dos on a weekend. They mainly seem to hang out in fast food places or just roam about the city centre (I’d not be so worried if she was at a house/cinema/etc). We’ve been saying 8.30pm home but she’s pointed out that that’s completely arbitrary because it’s dark before then and all her friends are allowed out until 11pm. Am I being too strict?
