Not fair

I am so annoyed. Two years ago when I was 22/23 I was driving 1 hour away to visit my boyfriend. My parents were so incredibly strict about me staying out late, never being able to spend the night etc. We aren’t together anymore but now my older brother who is 26 who still lives at home has his first girlfriend and he is able to go out as late as he wants. Come home way later than I ever did without and fuss from my parents. Even was able to go on a trip with her two weekends ago, no problem from the parents. And then this weekend she was sleeping over all weekend?! When I bring up how unfair this was they deny deny deny and claim that it’s different because I was driving far and could’ve been r*ped, MEANWHILE he drives just as far! They refuse to hear me out and why I’ve been annoying and claim that 24 is the magical age that you can do whatever you want. How convenient..
