I know my dad loves me but I feel he's too over protective and I want time away
So in the summer I want to go to Reading Festival for the full weekend (3 nights) with 3 of my best girlfriends, ill be 15 by then and you need to be 16 without an adult, my dad said he wasn't comfortable with me going with just my friends so I negotiated and said "how about if kim comes?". Kim is my sister, shell be 23 by then and she wouldn't be by our sides, but she did say she didn't want to camp with us so I said that maybe if she just stayed the day and went to a hotel just outside the festival then that'd be okay because it'd be a lot easier to get hold of her if she's in a hotel or shopping and all rather then trying to search a festival for her and her not being able to hear her phone because of the music! I understand where my dad is coming from but I think that I'm old enough and responsible enough to go away from him for those few days! And I feel asif he has trust issues but he always says "its not you, its other people" but I just feel that if he can't trust me not to go near those people or walk away from those people before I get in trouble then there is little trust at all! I'm frustrated and need to convince him to let me go because all my friends parents are very trusting and say "okay, ill give you a chance but if you mess this up then youre not going again until youre 18, you call me every day and you stay together" and I think that is fair as anything! But it seems I'm not even being given a chance here, I'm so frustrated! How can I convince him?
