This is mostly taken from a conversation my friend and her stepmom had, which I thought was funny and decided to adapt for Veronica Mars. Enjoy.
"Dad, you should go. We'll be fine."
"I know you will Meg, but I'm not sure leaving you alone is the best idea."
"Oh," Meg said, grinning, "so it's just that you don't trust me. You honestly think we would get drunk and throw wild parties if you guys weren't around. Even if I wanted to, do you think Lillian would let me?"
"It's not that I don't trust you and Lillian, Meg, it's just that I-"
"Don't trust my boyfriend?"
"I wouldn't phrase it like that."
"I know you wouldn't Dad. But that's what you mean."
"I just don't ever want you to do anything you don't want to because someone makes you feel like you have to."
"Dad, I got the sex talk already. Felix loves me. He's not some horny teenage boy just trying to get laid."
Logan flinched. This was equally awkward for him, but Veronica was away for a case. His seventeen-year-old, whom he was sure was already sleeping with her boyfriend of two years, was not the only one who didn't want to have this conversation. He knew if he asked Meg about her virginity she wouldn't lie to him, but he would rather live in blissful ignorance. He wished Veronica was doing this instead. Someone had to talk to her before he and Veronica left town for a vacation.
Meg continued.
"Between you and Mom, I have no idea who you think taught me to take anyone's crap. Ever."
She smirked and Logan laughed. Meg continued, but her voice grew softer.
"He has never tried to push me into anything I wasn't ready for. He loves me Dad. And he respects me and my boundaries. A little too much for my liking sometimes. You've known him since I was a baby. You know he's a good guy. And he's terrified of you."
"Any chance then that you won't have him in your room at all while we're gone?" Logan asked hopefully.
"Dad!" Meg replied indignantly.
"It was just an idea."
"We're teenagers. That's not happening. I mean, what were you doing when you were my age?"
Logan contemplated for a moment.
"Don't tell me you're thinking about whether or not to lie to me. Lil and I have both read your books. I don't know if respectful characterizes your conduct concerning the female population of Neptune. And Mom has mentioned that you were a total stud back then. Which is completely gross by the way."
"I did some stupid stuff when I was your age and I regret a lot of it. I don't want you to end up hurt. Or doing something you regret."
"I get it. You're my dad. You're going to want to protect me. And I promise that of I ever end up in a situation I can't deal with, I'll come to you and Mom. But I'm a good kid. You know that. I need you to trust me, even if you don't like every choice I make. Okay?"
"I trust you Meg. I can't help the protectiveness. And as far as I'm concerned, while we're gone, Felix will be sitting respectfully across the room discussing literature and talking about the joys of abstinence."
"I'm pretty sure the only literature we'll be talking about will be the Kama Sutra," Meg mumbled to her sister, who had come in time to hear the end of the conversation.
They both laughed.
"I didn't quite catch that sweetie."
"I said of course Dad."
