Listen to mom and dad. Trust me, they know a heck of a lot more than you think.

 They never leave their girlfriends. It doesn't matter what he says, or how crazy he is about you. You're younger and dumber than he is. When you reach his age, you'll realize he knew this. Good news though. If I know you...you'll get even.

 Shut up once in a while, confrontation is not sport. But never back down in front of that guy - he's still a dick.

 Put your heart in to everything you do including loving that boy with all your heart because at least you know you have a heart.

 Two beers is enough. Your brother's friend isn't as cute as he seems after eight. He isn't really as nice either. And he smells really bad. Don't let him stay the night. He WILL take advantage.

 I could tell you what's going to happen and give you some pretty good advice, but I'm not going to. Why? Because you won't listen. You won't take advice from anyone else, so why would you take it from me? No, you're going to have to learn the hard way. Maybe someday you'll grow up enough to listen.

 Just because you're on break with your boyfriend does not mean you can make out with random guys.

 You got there, even though you felt you'd never be found again.
