I know we don't always get along. In fact, there have been many times over the years that I've wanted nothing more than to give you a sharp kick to the shin (and I have a feeling the urge was mutual). The truth is, most of the time, I would do anything for you. That's what sisters are for.
It's hard for me to wrap my head around the fact that you're going to be off to college in the fall. It just doesn't feel like you should be old enough to do that yet. I think college is going to be good for you. It will challenge you far more than high school (or anything else, for that matter) was ever able to do. And here's my biggest suggestion to you: have fun. YOu sometimes get so incredibly wrapped up in being perfect (which is annoying as hell, by the way) that I think you sometimes forget to enjoy the whole ride. If I find out you're spending every free minute at ONU in a practice room, I might have to drive up there myself and beat you over the head with your own trumpet. I know you have to practice, but please, for all that's good in the world, spend at least a little time away from the trumpet. Join a club. Make new friends. Distance makes the heart grow fonder. And don't worry yourself into sickness if you find some classes in college are harder than what you did in high school. It happens. It's good for the humility. It's okay to struggle from time to time. It's okay to not be perfect all the time. You're going to need to grasp that concept sooner or later.
I love you dearly and hope the years ahead of you are filled with excitement and happiness and adventures. Make memories.
