Mum and Dad,
let me go, I'm old enough. You should know when you hang on to me, I feel even more answerable to you, when I shouldn't. I need to learn how to make my own decisions and to regret or be proud of what I decided. You have got to make me see the world the way I want to, not the way you already learned to see it.
How can I convince you that I'm no longer 15 and naive? I know what I'm doing. And I want to be able to define right and wrong for myself. You should know that I will never be entirely happy about being "independant" until you don't agree and accept.
I hate making comparisons, but I have to. I need be given a choice, or else, I am going to feel like I live in prison. I understand certain rules, and I've told you that I agree with some of them, but some of your rules have no logic behind them, and following them makes me feel restricted. I love you, and I know you want the best from me, but I turned out fine till now, and I could have done so much worse, yet I haven't. I hate that look on your face, that seems like you don't approve of my growing up. I know that's not true, but I feel this way only because I've done so much that is commendable and I've gotten nothing but "good" from the both of you. I need your support, but more than that I need you to trust me. And it seems like you don't, and that kills me.
I'm 20, Mum and Dad. You've got to let me go. Trust me... I'll be fine.
