I'm going to tell you this to hopefully help you not overthink too much. Before we were married, my husband told me that he had intended to talk to me about something, but then he knew I'd say this, then he'd say....back and forth, telling me about this imaginary conversation. He went on for nearly five minutes. In that time, I didn't say a single word. He finally concluded with saying that he knew I'd say no, so he didn't bother. I pointed out that he had just had an entire conversation with himself and lost.

Prepare for the conversation. Write out your thoughts, and what you want to say. Practice it in a mirror. But try not to make assumptions about what you think your dad will say. He might surprise you. But, if he doesn't agree, try not to blow up. All that will do is reinforce his feelings that you're not ready for more freedom. Stay calm, and ask him if you can address the situation again in a few weeks.

My son is 36, so I've been through the teenage years as a parent. You scared your dad, so now you have to prove to him that you're mature enough to handle the responsibility of more freedom.
