I'm going to disrespect my parents' rules regarding my relationship
Why do you want to be disrespectful of your parents?
I just can't stand them giving me advice on this matter.
Sometimes rules can be difficult to follow but as a child it is expected to follow their rules. Otherwise the relation with your parents will be damaged and a lot of fights will happen.
This is the 21st century and I should be free to do whatever I want.
Your parents care about you and most children don't receive that sort of treatment. Talk to them and let them know you appreciate their concern and see if they will be lenient on the matter.
