My mother told me when I was young teenager that she want me too you do better in life then she did. Of course when you are young and you think you can handle yourself in this world. You tend too get bored by your parents. One day you will appreciate their advice. You have too learn things on your own. And your parents are probally afraid of lose you too something tragic. I hope that helps!~
I think ultimately, your parents are trying to keep you from making the same mistakes that they did. But yes, they need to let you make/learn from your own mistakes so that you can become your own person.
