Equal standards
Back in the day, usually, the son would get an easier time around the house because they were just a male. It was more of an old-school outlook that parents had from a few generations ago. But now things have changed, sons and daughters should be treated the same no matter what.
While this may suck for the son, it’s only fair towards his sisters who want to enjoy their youth as well. As long as everyone is safe and having fun we see no harm in this, the 1 am curfew is a bit late for us though, our parents made us come back at 10 pm.
