What would you do?

if you had a 21 year old daughter who was in her senior year of college, but still lived at home to save money, and she was consistently 30 to 45 minutes late from the time you told her to be home after spending time with her boyfriend at his house (she sees him everyday and they’ve been together for 6 years) because she keeps falling asleep there and forgetting to set an alarm, what would you do? (I asked her to be home at 4am and she showed up at 4:30).
