I know that you think your parents are blocking your fun, but trust me everything that your parents are telling you or are doing will make perfect sense to you someday. Your parents are just being parents, let them do their job. If your parents think those friends of yours are ciyal suuq, than probably they are, remember parents are never wrong.
I remember as a kid, my patents were really strict too, I wasn't allowed to spend the night over at anyone's house ,except family and walibo only certain family members at that, and among other things. My mother's favorite saying was "Someday you will understand". I thought she was being paranoid and mean at the time. Now since I have grown that phrase makes sense, the light bulb finally turned on and I understand what she meant.
