my relationship with my parents

Hello , I'm Marc.
My parents scold me because I don't tidy my room when I arrive late at home.
They are very exaggerated with me , it is my room that's not their problem .
Sometimes I feel tired to hear the same things, I don't care what they say
because I know my obligations.
I know, I'm a teenager, but I need a little bit of personal space for my privacy,
at least make my opitions without their comments.

What can I do?
thank you

Maybe yuo could tidy your room once a week Marc. It certainly is't a pretty sight when you open de door and see all this mess.
