How late can you going out?

I'm 19 now and in college so the only times I am actually home with my parents is during breaks. I think up until I reached my junior year in high school by parents were pretty strict on the times I could go out. They wanted me back around 10 - 11 on the weekends because they knew at that point I did have curfew to obey by. By the time I was a junior the restrictions weren't as bad and then it was midnight at that point. To them there was no reason for me to be out any later. But they did have a policy which was they weren't really going to tell me what I could and couldn't do, because they felt if they said no I was going to be more likely to rebel. Their logic worked and I think the worse thing in their eyes I did in high school was lose my virginity at the age of 15 but I never got pregnant from it. Once my senior year in high school hit my parents let me stay out till 4 in the morning if I wanted to. The only thing they asked if who I was going to be hanging out with and about where I was going to be and when I planned to be home therefore if I wasn't home they knew something probably happened. At the point I graduated high school and started college my parents knew that I was use to leaving this whole independent lifestyle. Now they don't ask me any questions and I can come and go as I please. I do have some respect for them though to the point I'm going to tell them where I'm going and about when I get home. To me its their house not mine and therefore they deserve that respect. The only rule that still goes though is no boys sleeping over.

I am 18 now, so my parents are all "well you can do what you want, I can hardly ground you for coming in late" or as my Mam says "if I grounded you for being late, I would have to ground your Dad too". I am expected to be in before 11pm unless I say that I am going to be out late, but if I say that I am going to be out late then it is fine. The latest I have come in is about 3:30am. I am also allowed to just text and say "I am sleeping over a friends, not coming home tonight". It is fine as long as she knows when I should be home and if I am going to be later than I said just to text.

I am 47 years old and do not live with my mom.But,I did off and on as an adult.She never did tell me when I needed to be home.However as a curtosy to her I would call her if I was staying at a friends,so she would not worry that I was in an accident or other harmful ordeal.She does worry and I do not blame her.See,someone did break into my home one time and almost killed me.I am not partially handicapped from those injuries.I have rarely been a person too stay out real late anyway.And if I have ever had plans to go out very late or away from this area I still call my mom and let her know what my plans are so that she won't worry.
