Dear daddy letter?

I need help to write my dad a personal letter. I'm 15 and I don't have any freedom outside of my house. He can't except that I have a boyfriend, that I want to sleep over friends houses, or go shopping, or spend time with my friends, go to parties, friends houses. Just Anything.. I need an heart warming letter explaining to him that I'm not his hopeless little baby anymore and that I can stand on my own two feet. that I don't need him to be there with me every step I take.. I really can't take being there anymore.
