ОТВЕТЬТЕ ПОЖАЛУЙСТА НА ВОПРОС.
My mom is normally cool with most of the things that I do. She understands that I need my own space. She has nothing against make-up and she likes all my friends. Last month I introduced my boyfriend to her and she was great. My boyfriend was really impressed. The only problem I have with her is when I want to come home late. All my friends go to clubs and stay out until ten thirty, but I have to be home by nine o'clock, so I miss all the fun. If I'm ten minutes late, she gets mad with me and nags me for days after that, what can I do?

I guess you should talk to your mom like friends. Ask her to remember herself when she was as young as you. You can also invite your boyfriend to talk to you both too. I think if he promises to protect you, to take care of you she can agree. Just ask her to try once, not for a long time, just half an hour for the first time.
