towns an hour or more away from home. I never had a curfew (set time that I had to be home) but the rule was that I had to check in at 10 or so and then call when we left to let my parents know when to expect me.
For my parents it was more about making sure they knew I was safe than an arbitrary time on the clock. Maybe there is a conversation along those lines that you can have with her. It isn’t about the time on the clock as much as it is that you need to know where she is and that she is safe. That’s your #1 job as a parent.
Like...11:30 curfew missed by 75 mins without any heads up would worry me sick as a parent. But an 11:30 phone call or text saying that the party is going longer than expected and asking if it is ok to stay out later wouldn’t worry me at all.
