Don't lose your driver's license; it will ruin your life.

 You're gonna get kicked out when you're 17, don't drink. Trust me. I don't want what happened to me to happen to you.

 don't get caught up with the fact that people actually want to be your friend. Go to class, get your homework done. It will be better in the long run.

 Beware when you hear the words 'He's just a friend'

 I know you said that you'd be together forever and get married and have two children and two dogs and a nice house and live happily ever after, but that dream wasn't supposed to happen with him. There's always someone better waiting for you just around the corner. You left for a reason.

 Don't fall in love easily. Have fun while you can and live like there's no tomorrow.

 Your peers seem childish now because they really are. Just wait until college, though, because there, the people who laugh at fart jokes are the minority group. Stay patient and you'll come through fine.

 He still likes you (us) too. Believe me. Remember that even though he gets busy, your (our) friends can get the dirt for us.
